CK3 Dev Diary #98: the Castle's foundation

Hello there,

The release is approaching and before sharing the release notes with you next week we have a few topics to cover! Today we will be focusing on what is going to be added in the free update "Castle" released along Fate of Iberia. For the modders, you will also find the updated documentation attached to this post, in case you want to have an early look at the new functionality!

Clan Contract​

Since Iberia in 867 has several clan realms that play big parts in the region, we wanted to add some new options to clan contracts:
  • Marriage Favor: the goal is to get benefits in exchange for a promise. Not fulfilling it will have consequences though..
  • Ghazi: encourage your vassals to wage holy wars, but get less levies from them
  • Iqta: less tax and levies but better synergy for Men-At-Arns for both parties
  • Jizya: unlocked by the Tenet of the same name, this is a specific contract for people of a different faith, increasing their tax but lowering the levies their liege receives

The image shows the new special contract for Clan Government
There are now cool options to get the most of out your vassals as Clan Liege now.

We are looking forward to working more on clan governments in future updates as this was a first step to making them as complex and interesting as they were historically.

Dissolution Faction​

To model some of the big historical shake-ups in Iberia, we’ve introduced a new faction type. The Dissolution Faction will aim to destroy the primary title of the top liege of the realm, as well as any other same tier title. This makes all vassals independent, shattering a kingdom or empire. In FP2, this means that the Umayyads can collapse as they did in history, but it also means that any large realms in decline will face this challenge.

Anything detracting from a realm’s unity will increase the risk of a Dissolution Faction forming. That means short reigns, low cultural acceptance, war losses, and unallied vassals will all be dangerous to King and Empire tier rulers.

Realms where the vassals either like the heir or can elect their own are less likely to face a Dissolution Faction. And if a vassal can make a claim for the title themselves, they’ll do that instead.

The image shows the Enforce Demands of the new Dissolution faction: the primary title will be destroyed, granting independence to all the vassals of the target
There is a high chance of the Umayyad falling when starting in 867

Map update​

To go along the theme of the flavor pack, we’ve updated the map for Iberia. The map changes are fairly small in scope this time around though, and the focus was to update northern Iberia, more specifically the kingdom of Aragon.

In order to improve the overall accuracy we added new counties such as Rossello and Pallars. For a better depiction of the area, existing baronies were moved around and new ones added in order to increase the granularity of the area.

The image is a close up to the area that changed the most, showing the new county set up
In addition to the county set up, the terrain type of some provinces also changed.

In addition to the changes in Aragon, we added cultural naming variations for many Berber and Arabic cultures to many titles across Iberia.

Shared Head of Faith​


Heads of faith can now be set as characters of a different faith. This is done through script, rather than manually in-game. This means for insular Christians, Conversos, and Mozarabs, the Pope will be their Head of Faith, even though they are of a different faith.

The image shows that the Insular faith now have the Pope as their Head of Faith


Historical faiths can be emulated by using the Rite tenet. Provided you don’t meet certain red lines for your old Head of Faith, at the cost of a tenet slot, you can keep your old faith’s Head of Faith while converting.
Ecumenical Christians taking this decision keep ecumenism, making them “astray” from the Catholic perspective.

The image shows the tooltip of the new Rite tenet


Islam now has a bespoke system for choosing the correct caliph: though Shias are still fairly split between several caliphates and imamates, the mainline Sunnis (Ashari, Muwalladi, and Maturidi) now share the Sunni caliph as a Head of Faith. Muslims who share a Head of Faith view each other as ”righteous”.
Influential members of an Islamic faith whose Head of Faith doesn’t share their faith can attempt to Appoint a Righteous Caliph, claiming (and creating) the caliphate for themselves and splintering the Ummah.

The new decision allowing to appoint a new Caliph


Once splintered, a faith cannot be brought back into the fold. Islam is stronger together, but its differences often become irreconcilable.

New temporal Sunni and Shia faiths cannot appoint themselves as caliphs immediately if there’s a caliph available (either the orthodox version or their prior faith’s caliph). Instead, they must show submission to an existing caliph from whom they derive their authority, even in rebellion, and then follow the path to Appoint a Righteous Caliph themselves. Characters intending to do this all along can get a little boost on the path.

History Changes (and friends!)​

Visigothic is Visigone​

As I’m sure some of you have noticed in the streams and such, we’ve removed Visigothic from the map 867, starting Iberia off pre-split between the 1066 cultures (save for Aragonese, which now emerges as part of the creation of the Kingdom of Aragon).

There’s a few reasons for this - Visigothic was always a bit of a wonky culture, a holdover from CK2’s Charlemagne DLC that made mapping 9th century Iberia very inexact but which added some fun flavour to the region. Since cultures before 1.5 were mostly cosmetic, it didn’t really affect actual gameplay much, even if it fudged history somewhat (not least by making the Visigoths hang around long after they’d diverged or hybridised).

The release of Royal Court changed that situation, making playing in Iberia a very weird flow. You start, you have one set of traditions, then within a few decades an event shifts your culture and you almost certainly end up with a radically different set of traditions with no feasible way to do much about it.

This, plus just being bad history, clinched it for Visigothic, and we had it taken out to the block and given the ol’ Royal Anti-Pardon. As with Suebi and co before it, Visigothic will continue to exist in the files, along with its associated namelist, where it remains useable for history and in mods and such.

The image shows the new culture set up in Iberia. Andalusian in the south, and the north is split between Galician, Astruleonese, Castilian, Basque, and Catalan


Fresh Faces & Further Foes​

Further on from this, we’ve updated, added, and occasionally removed hundreds and hundreds of characters all across Iberia (as well as a smattering in Occitania - if we never read about another character named Bernard, we’ll be happy), adjusting relations, lifespans, traits, and dynasties.

This’ll add a bit of life in both major bookmark dates, but most importantly, it’ll be a bit of colour for those of us who enjoy spelunking the history databases and checking to see if titles in-game have their Migration Period rulers properly associated. Title-nerds need love too. On that note, the Visigothic Kings now have a titular historical title to give them their correct royal dignity & regnal numbers.

For folks who like actual gameplay more than interactive reading, we’ve added the Mozarabic strand of Christianity - Arabicised Catholics who carry on the strongly independent liturgical and ecclesiastic traditions of pre-Islamic Iberia but view the Pope as their Head of Faith (with the aid of the Rite tenet).

Squeezed between the Catholic North and the Islamic South, the Mozarabs struggle to preserve their way of life, and since you can see a lot more of them in 867 than 1066, you can probably guess how it’s going for them.

Previously, we’ve portrayed the sparsely-regulated Leonese portion of Iberia’s Inner Plateau as being, variously, either under nominal Andalusian control (since they notionally held it) or nominal Asturian control (since they grabbed it soon after the Andalusians stopped caring about it).

Neither of these were quite perfect solutions, and relied on fictitious local characters either way, so we’ve now given this rural area over to a collection of minor Mozarabic characters. Abandoned by their Islamic overlords, eyed greedily by their orthodox brethren, these minor landholders soldier on as they have for centuries. At least, they try to, but it’s a difficult life being a one-county minor wedged between larger realms…

It’s not all doom’n’gloom for Iberia’s new minors though, because, on the subject of those larger realms, we’ve also split them up a tad! Asturias has lost Portucale, which they’re actually only in the process of trying to snatch, whilst Andalusia has been given a reality check. Both Portucale and Toledo, whilst paying nominal homage to Cordoba, were functionally independent, with Toledo in particular resisting repeated military expeditions and attempts at taxation.

The image shows the new Realm set up for Iberia. There are now more independent Kingdom between Al-Andalus and Asturia


Andalusia is in the process of making a play to subjugate Toledo more firmly in 867, with Portucale also being on the books, so we represent this as a brace of wars on start. Andalusia is trying to quell its powerful border districts of Toledo and Portucale, keeping them in the realm, whilst Asturias tries to snatch Portucale mid-rebellion.

Finally, Asturias has been tweaked, losing its starting title law of feudal elective. The current king’s father decisively abolished the notion of the nobility electing their kings in the short term, and his son carried that on, so they start sans-title law now. In addition to this, Castile also starts with de jure territory in 867, making it creatable in the earlier bookmark - if Castile actually is created for any reason, Asturias is reduced to Leon. If Asturias is able to de jure drift Castile into itself before Castile can be created, then the union is preserved and Asturias earns its right to perpetually exist for 867 starts.

I like the dissolution factions in theory, but I do worry that this means the Byzantine Empire is going to pretty much instantly collapse every game. What with their constant civil wars, the bar for factions pressing their demands tends to be really low which seems like a recipe for disaster with dissolution factions.

Destruction faction sounds great, hopefully tribals will have a buff to them forming, can help show break up of kievan rus, hre interregnum, and poland losing silesia to the germans for 600 years

If you have a shared head of faith, does that mean you join the same holy wars?

Will Mozarabs be able to join crusades called by the Pope? Will Catholics in France come to the aid of a Mozarab king in Iberia facing a Sunni holy war?

So El Cid will be landed in 1066 now?

There are still several questions though.
1. Will the Holy See still be limited to Catholic only?
2. Have you tested the dissolution faction? Will its existence weaken other factions which are available now?

I hope Dissolution Factions means that you can make non-Western Europe not all start with Partition like they do now since there are other means of shattering large realms. All this flavor for Andalusians is cool and all but watching them split because of Partition succession is very immersion-breaking for me.

This is great stuff, thank you!

out of curiosity (and please correct me if I misinterpret this) does Jizya also mean that the vassal can’t/or the AI won’t convert their religion if it is applied? It’s my understanding that it’s a tax applied for the protection of being able to practice one’s faith so is that taken into account at all?

i get that it would be useless and go away if a ruler converted to Islam but it would make sense to (again from my understanding) make it so that ruler and their lands are harder to convert too in exchange for the taxes/protection.

The Dissolution faction seems a really good thing! But I'm afraid that the Byzantine Empire or other important AI Empires will explode after 100 years if not keep on check (which would suck for historical nerds like me but will also displease players who love challenges and will have to face 200 micro nations insted of a Big rival).

Perhaps the Dissolution Faction can be put in a Game Rule?

Is the centralization (crown authority) of the kingdom have an influence on the dissolution factions ? It would seem strange that a very centralized France would just vanish in thin air just because of one bad succession - it would seem that several liberty factions could suit better first, then once the country's crown has just fictional power over the country, the proper dissolution is the logical next step.

I'm really excited for this new possibility to shatter big empires (including mine), all the more when they are huge without a really strong emperor !

Paradox, this looks amazing. I absolutely love the rite mechanic and I am interested in how Byzantine Catholic rites such as the Melkites in Syria will be done.

I also think the struggle is awesome and I can’t wait for that to spread outside Iberia. May I suggest a religious struggle system for the 1054 east west schism? I understand why orthodox and Catholicism is split in 860’s but I would like to possibly even see catholic and orthodox go to hostile relations. The Seljuks often disintegrate and are of little threat to Byzantium. Perhaps beefing them up and having the Catholics and orthodox participating in joint crusades could be apart of this new religious struggle system to help heal the schism

things to consider:
There is no gothic culture in crimea.
Apostolic and aniconism don’t mix historically due to the fact that apostolics have icons. Asceticism is likely a better tenant here.
No ottomans. Struggle system in Asia Minor. Ottomans can help in Byzantine civil wars in exchange for duchy titles just like in history.

edit: the pope should be head of orthodox faith until 1054. Events for orthodox could be made to form schism earlier.

Already planning my campaigns around those achievements.
Haesteinn would be too easy, gotta choose some other unlikely outsider, like the Emperor maybe, just a few centuries before some parts of Spain were under Eastern Roman rule
 
I have questions about the Rite Tenet.

  • Will it be available to Pagan Faiths?
  • How will it work with non-ecumenical Christian Faiths, or Jewish Faiths?
  • Will it be possible to create a shared Head of Faith title if it originated with a different Faith?
  • How will crusades and excommunications work?

Since you added another faction targeting the top-level ruler, wouldn't it be a good opportunity to add factions that are loyalist and/or try to counter-balance rebellious movements within the realm?

Especially vassals with very good contract conditions should have a huge desire to keep the realm alive.

Will muslims declare jihads now? I have 600 hours in Ck3 and never saw a jihad once. Usually Caliph is too weak to declare it and other muslims, especially vassals don't join.

Even when player is the Caliph then declaring jihad is not worth it - other muslims don't join but on the other side you have whole catholic/orthodox world.

Are faiths with the shared HoF able to have one of their own elected to be the Head of Faith? As in are Mozarabics, Insular or Conversos able to get one of their own to be elected as Pope?

When the Catholics call a Crusade are the faiths with share the Pope as HoF able to join in the Crusade?

Are Catholic rulers able to join a defensive Holy War on the side of a Mozarabic/Insular/Converso ruler?

If Aragonese emerges as part of the creation of the kingdom of Aragon. Does the culture of the founder have any influence on what Aragonese is considered to have diverged/descended from? And do you get to choose any tenets for it when it's created?
