House Helmast is a Loyalist Imperial Knight House of the Imperium. There is very little information in Imperial records about this Knight House, other than their valiant stand on their homeworld of Alaric Prime against the invasion of Ork Warlord Grukk and his Red WAAAGH! in 998.M41.
- Defence of Alaric Prime (443.998.M41) - In 998.M41, Warlord Grukk of the Red WAAAGH! ploughs into the densely populated Sanctus Reach, his crusade's juggernaut momentum smashing past the Space Marine homeworld of Obstiria to plunder the planets beyond. The Imperium prepares to make a stand upon Alaric Prime, a Feudal World of linked archipelagos and crumbling gaols. When a flotilla of Ork rust-ships make planetfall, the knightly houses of Alaric lead their Cadian allies in a worldwide counterattack. Warlord Grukk's bullish tactics take a heavy toll on the human defenders before the legendary Freeblade known as Gerantius, the Forgotten Knight, joins the conflict, tipping the war into a new phase of desperate battle.
