I've noticed that CK2 has at least 2 interesting character lists: Interesting Characters Guide on the wiki and A List of Interesting Female Characters on the forums. So I decided to make one myself. If you have any suggested characters, then give us their name, starting date and a short description of their situation. The list is in no particular order, but I may change it if it proves to be too confusing.
I'll start:
Lord Monterys Velaryon of Driftmark, A Feast For Crows: One of the two characters in Westeros with High Valyrian culture at this start date, the other one being his uncle. Monterys is a 7-year old child and a vassal under Stannis, but he follows the Seven.
Lord Selwyn Tarth of The Straits of Tarth, A Feast For Crows: A 54-years old wifeless lord which is not engaged in any wars. His heir, Brienne of Tarth, has Celibate trait.
Lord Ferret Crabb of The Whispers, Bleeding Years and Aegon's Conquest: A 59-years old man with only one province. The province is mediocre at best and borders lands of Aegon the Conqueror. He is also one of four independent count-level lords in Seven Kingdoms and he isn't a de jure vassal of any other character.
Lord Arthor Magnar of Skagos, Blackfyre Rebellion: Leader of Skagosi Uprising which lasted 40 years. He has a much smaller force than Jonnel Stark and no good alliance options, as he worships the same gods as Wildlings.
Tormund Gianstbane of The Haunted Forest, A Feast For Crows: Tormund is bordered by the rebels of Craster's Keep, Hardhome, The Night's Watch and White Walkers. He's also the strongest independent Wildling in this start date.
Prince Doran of The Dorne, Robert's Rebellion: You aren't engaged in war on any of the sides, but your sister is a wife of Rhaegar Targaryen and some Mountain might be Riding to Dragonstone...
Archon Tycho Zokan of Tyrosh, War of the Ninepenny Kings: Technically a ruler of Tyrosh, but he has only one province, Little Tyrosh, and he is also at war with The Golden Company. Rest of his rightful lands is in the hands of Maelys Blackfyre.
Lord Howland Reed, A Feast For Crows: One of closest (living) friends of Ned Stark and a great warrior despite of being a Crannogman. Meera and Jojen seem to never return unless they inherit, but Jojen also often dies of poor physique.
Lord Gilbert Farring of Farring Cross, A Feast For Crows: Gilbert worships R'hlorr, but his small folk still prefer the Seven. Farring Cross borders King's Landing and its 33000 angry Reachmen, while Farrings have all their forces in Castle Black.
Feel free to add your suggestions.
