Lheorvine Ukris
"Drop your weapon, Captain Abaddon. We’re here to steal your ship." - Lheorvine Ukris during his first meeting with Ezekyle Abaddon
Lheorvine Ukris a.k.a. Firefist (just don't call him that to his face) is a former World Eater, founding member of the Black Legion, and one of the snarkiest motherfuckers in the galaxy. Known to his friends as Lheor, he got the nickname Firefist after a plasma cannon blew up in his hands during the Siege of Terra. He's a good example of a (relatively) reasonable Khornate, as he loves battle but isn't a mindless berzerker like many of his comrades, and sees the value of ranged combat, personally wielding a heavy bolter.
After the Battle of Skalathrax scattered the World Eaters, he commanded a warband known as the Fifteen Fangs. Not much is known about him during this time, except that he exterminated some faggot Word Bearers.
He was one of the survivors of the Battle of Harmony and became a commander in the Black Legion.
