House Perdaxia is a Renegade Knight House that repudiated its oath to the Imperium of Man at the beginning of the Horus Heresy.

The history of House Perdaxia has all but been scoured from existence -- not by the agents of the Emperor, but by His enemies. Their Knights march to war with their old heraldry scratched off and covered by the colours of the Traitor Legio Fureans, leaving only speculation as to who they once served.

House Perdaxia's personnel used the names of deities from the pre-histories of Terra's Indic regions, prefixed with an impenetrable code consisting of numbers, letters and more obscure runic symbols.

House History

Notable Campaigns

  • Invasion of Paramar V (673.006.M31) - Fanatically loyal to the Legio Fureans, House Perdaxia heeded the summons of Archmagos Inar Satarael alongside their Legion when the Traitors invaded Paramar V. During the fighting of the First Battle of Paramar, the Perdaxia Scions sacrificed themselves in their hundreds to defend the Tiger Eyes' Titans, taking dozens of Loyalist Titans down with them.
  • Battle of Beta-Garmon, "The Titandeath" (006-013.M31) - House Perdaxia took part in the long and savage Beta-Garmon campaign, which included hundreds of war zones across dozens of worlds. During this conflict, House Perdaxia provided Knight support to the Legio Fureans. Even before the greater armies of the Warmaster Horus reached the star cluster, the battle lines had long since been drawn, and fighting had been going on for many Terran years. It was a cauldron of battle that would consume millions of lives before its end and see the demise of entire Titan Legions, earning this campaign the dire moniker of the "Titandeath." The Beta-Garmon Cluster, also known as the gateway to the throneworld of Terra, was the last hurdle that the Warmaster Horus' forces had to overcome before they reached the Imperium's capital world. Heavily fortified by the Loyalists, Beta-Garmon would become one of the greatest and bloodiest battles of the Horus Heresy, as well as one of the longest-lasting.
