(Sorry that this took a while! Since I couldn’t decide a character, have a bunch of facts for different characters:)
Marika sort of sympathizes with the Scarlet Crusade. Though their methods were too aggressive and they discriminated against almost everyone, her hatred of undead is strong enough that part of her respects the Crusade’s aim to destroy them with almost any means available.
Merces likes to study gadgets and other mechanical things by disassembling them, examining the parts and then figuring out how they work. Unfortunately, he isn’t yet as skilled at putting things back together… though thankfully he at least never disassembles anything he hasn’t bought with his own money.
Chasim likes to go fishing, and he doesn’t really care what he catches. A nice fish? Great, now he can make fish soup for dinner! An old boot? Oh cool, that’s funny!
Eodain is afraid of fire. He can tolerate the sight of it, but he won’t e.g. sit in the seat nearest to a fireplace nor carry a torch if he can avoid it. The story involved in the explanation involves a treasure hunt, a trap floor and one Dwarf (who is both his friend of sorts and the person whom annoys him the most).
Viridiel is relatively good at languages and can speak Orcish pretty much without a foreign accent. He’d probably learn other languages quickly as well - if he bothered to study them.
Ilendre has self-published a poetry book, which has garnered some interest. Another one of my alts - a young Blood Elven noble called Delarion - is a fan of hers.
