Machaon was one of the few Marines to survive the [[Fall of Sotha|invasion]] of the Chapter's [[Adeptus Astartes Homeworld|homeworld]], [[Sotha]], by the [[tyranid]]s of [[Hive Fleet Kraken]]. He was responsible for aiding in the recovery of [[Spiridonas]], a [[Librarian]] who was forced to act as a pseudo-[[Navigator]] in the retreat from Sotha and who suffered from massive levels of [[Psyker|psychic]] strain as a result of piercing through the [[Shadow in the Warp]] and guiding the Scythes' survivors to their muster point in the [[Miral System]].{{Fn|1a}}{{Fn|1b}}

The tyranids would later attack the Miral System as well. The bulk of the surviving Scythes of the Emperor made their stand at their bastion on [[Miral Prime]], the [[Giant's Coffin]], but when [[Chapter Master]] [[Mansirius Thorcyra|Thorcyra]] was killed, [[Space Marine Captain|Captain]] [[Thracian (Scythes of the Emperor)|Thracian]] declared the planet lost and ordered its evacuation. Machaon was killed returning from the [[Apothecarion]] by [[Hadrios]], who believed that that the Apothecary may have been [[Genestealer's Kiss|compromised]].{{Fn|1c}}
