Changes

It is thought that Kossolax was originally known as '''Solax''', [[Space Marine Sergeant|Sergeant]] of the World Eaters 3rd Assault Company, before the [[Horus Heresy]]. This theory is largely based on sightings of the ''Barbarus'', a [[Rhino]] transporter which belonged to Solax' squad and was reportedly present during the Siege of the Emperor's palace at the height of the heresy. Since then, the ''Barbarus'' has been spotted on numerous occasions throughout the millennia in service of Kossolax.¹

In 444.[[M41]] Kossolax joined his [[Primarch]] [[Angron]] in his [[First War for Armageddon|invasion]] of the imperial hive world [[Armageddon]]. At that time Kossolax' veteran warriors had already proven themselves in eight campaigns against the [[Imperium of Man]].
