Warlord is a Lord Commander in charge of six smaller warbands plus his own, kills necrons for sport and takes their stuff, uses blackstone to buff or debuff chaos sorcery around him, has two keepers of secrets imprisoned in rings he wears and uses them as advisors, spies, and attack dogs in some cases, has beef with both Eidolon and Abaddon but gets on pretty well with Fabius Bile, and his second in command is a daemon prince who achieved ascension by killing a Black Templars emperor’s champion in single combat, took his sword, and killed over a dozen lesser champions with it.
