The Fellblade was a super-heavy battle tank fielded by the Legiones Astartes, a towering war machine that stood among the most powerful armoured vehicles a Legion could deploy short of a Titan. It was the Space Marine equivalent of the Imperial Army's Baneblade, adapted and refined for the transhuman warriors of the Legions.
Its primary weapon was a colossal twin-barrelled accelerator cannon capable of obliterating enemy armour and fortifications with a single volley. Flanked by secondary lascannon, heavy bolters and a demolisher-grade turret option, the Fellblade could dominate an entire battlefield, its passage marked by shattered strongpoints and burning wrecks.
Rare and revered, each Fellblade was a strategic asset guarded jealously by its Legion. The Sons of Horus and Iron Warriors counted such engines among their heaviest hitters, unleashing them where the fighting was thickest and the enemy defences most unyielding.
