Oh boy, that is like... 𝑠𝑜𝑜𝑜𝑜𝑜𝑜𝑜𝑜 many ocs to choose from. Hmmmmmmmmm, how about Vallan: https://toyhou.se/120384.vallan-aislin

Vallan is a nixian which are essentially war mongering cat elves in an unnamed fantasy world of mine. He’s a semi-retired witch warrior living the life of a trophy husband with his warlord wifey, Sifrid. A fun fact about him is although he’s poly (as is his wife), he is 100% ride or die for his wife. He loves Sifrid beyond reproach and would slaughter gods for her ♡

Another fun fact is Vallan was a warlord himself and when Sifrid bested him in 1 on 1 to the death combat, instead of killing him as was the norm, she gave him a choice: serve her until death or she frees him, or die. Vallan chose to serve her. The contract was magically binding so Sifrid had no worries he’d betray her. Vallan’s army and territory became hers and, over time, Sifrid and he grew close and eventually fell in love. There’s more to it, as it took a while, but that’s the gist.

Also Vallan likes fire and he’s most skilled with fire based magic.
