You are correct! When I was making my character, I soon realised she ended up becoming Yuria with the serial numbers filed off so I just decided "well, why not rip-off Souls even more?"
Well, my lady, Inverness of Tarrow, was devised as a knight (actually a homebrewed hexblade warlock, we were playing in DnD 5e) who would fall to one of the dark forces we're antagonising in the campaign and struggle with an allegiance to a higher being of much greater power than any mortal could imagine, while also remaining loyal to her party. This caused one of the party members (in-character) to abandon the group entirely.
...it just so happened that the edge quickly wore off after my soft ass realised I couldn't deal with being mean in-character, plus the others being very cute. Due to being charismatic, she drifted into a leadership position in the party, and had a full redemption arc which ended in one of her arms being lopped off to sever her connection to her patron.
She keeps the dark aesthetic while trying to make up for her misdeeds via just being as cosy of a person as she can. That explains the Goth and the Party Mommy.
As for the Finnish... long story short, the nation she hails from is basically fantasy Finland and she was always described as having a pretty strong accent, being far too used to monstrous beasts and other crazy shit that happens in her country, and enjoying saunas a lot.
All because I made a ripoff of Yuria of Londor that went a bit too far with stealing from Dark Souls.
Make you a PC who can do both. Someone who can brood in dark corners with the best of em, but who also routinely makes sure the party is fed thanks to their chef feat.
'tis what I try. I regurgitated her full story in another reply but I do try to balance the brooding and the unhealed pain with party momminess and so far it's working.
She might just need a hug or several herself every now and then but she's a good boss.
