Katheryne would be a cleric, she’s very gentle, dislikes conflict, and hates seeing people hurt.
For weapons, she would have a mace and a shield because while generally passive, when pushed to the breaking point she snaps and becomes very scary.
My other OC Bacon would definitely be a barbarian. They’re very strong, stubborn, have anger issues, and aren’t too bright. For a weapon they’d either wield a claymore or a two handed great axe.
