It's a realm, not a character. They were on BT, and they died in the Third Invasion because when they were losing the war they started against Riombara, they absolutely refused to accept any peace that didn't amount to Riombara surrendering (for instance, they insisted upon taking several regions from Riombara in any peace treaty), and when the Invasion came, they still wouldn't give up even to fight against the monsters, undead, and daimons.
So the monsters, undead, and daimons wiped them out.
Thank you Anaris. See how little I knew, I thought it was a person, not a realm.
