|This article is about the The Character Bubonicus, for the The Daemon World Bubonicus see Bubonicus (Planet)|
Lothar (now known as Bubonicus) was a mortal Champion of Nurgle, born on a backwards planet which remains cut off from the Imperium by warp storms. Raised to daemonhood, he now rules a daemon world within the Eye of Terror, also named Bubonicus.
During the Horus Heresy, Bubonicus was one of many daemons summoned by Erebus, First Chaplain of the Word Bearers, by a dark ritual conducted during the Battle of Calth, presumably as a prelude to Horus's attack on the Imperial Palace during the Battle of Terra.
