Okie-dokie.
I’ll limit myself to one - I’m playin’ in a 5Ed D&D game and I found a fantastic Sorcerer bloodline, and immediately had an idea.
Halifax is a man of two natures. Ascerbic, frustrated and generally short tempered; Halifax is a Hellfire Tiefling, Phoenix-blooded sorcerer. Feeling pinned between two natures - the Phoenix, symbol of hope, cleansing fire and rebirth, the renewal of good and eternal life... and Demonic blood (Yes, Demonic). Spite, chaos, destruction and hatred.
Angry at his parents for abandoning him as a freak of magic, angry at society that forced him to survive as a pickpocket, angry and how terrible things happen to people who did nothing wrong, Halifax is stuck... in Ravenloft.
But, why would Halifax be worth playing? Why be such an angry man? What is there to experience in this frustrated and determined man in such a horrible place?
Well, my enjoyment is based around finding new lenses for the world. Halifax DOES learn to trust. He does not turn off, he does not accept shitty circumstances as a reason to stop trying. Halifax does not accept the foe-shipping that Wren (Warlock, party leader) does, but is slowly warming up to the idea of falling for the bitter, handsome priest...
Plus, we have a Dragonborn Paladin of Redemption who has a magical swear jar, and is downright adorable 10/10. Halifax and he are buddies, and it’s fucking awesome. I wrote a story (With many more editing passes than this post!) about Archie and Halifax: https://professorjimbles.wordpress.com/2019/02/04/horn-and-flame/
