The Twili, Ikana, and Lorule are planned for invasions. The Lost Woods is pretty much solely populated by undead, mostly skull kids and then there's Gooey swamps which was a stalfos pirate stronghold.
Sounds awesome! Just wish they were playable!
My 'opinion' on Termina is that it is the future of Hyrule, sort of like the apocalypse. Ikana is the remnants of Hyrule, torn apart by civil war and the Garo. Clock Town is the 'survivor' of these civil wars. This explanation fits in with the fact that all of the major races of Hyrule are present in Termina. The 'Golden Goddeses of Hyrule' are said somewhere in Skyward Sword to be the Gods of Light. I say Majora is the God of Darkness, and that he has a piece of the Triforce, which became Majora's Mask.
Enough with my theories, it's time for more suggestions.
I really think every race should be playable in some form in the final version, even if they have no flavor events or decisions.
Regarding Termina, I might eventually start a submod myself regarding my theory above.
I hope you guys do a race mechanic similar to Elder Kings. But also, I think you should have Blood Traits like the Lux Invicta mod, though not nearly as many, but like
Blood of the Hero
Blood of Hylia
Blood of the Gerudo King
Blood of the Sage of Light
Etc
Also, I suggest makeing more event chains regarding duels. Boss battles are a special thing in the Zelda series and there should be special types of duels. They should also be more frequent in battles.
Cultures should have rivalries with certain other cultures, like the Hylians and the Gerudo, and so on.
I'm interested to see what your plans are for a Demon King if he should take over.
