A Halberd of Caliban is an archaic Power Weapon commonly utilised by the Company Champion of the Dark Angels Chapter's 1st Company, which is called the Deathwing. The Company Champion of the Deathwing, a member of the elite Inner Circle of the 1st Company called the Deathwing Knights, traditionally carried this massive weapon as his primary close combat defence. The Halberd of Caliban's blade was reforged from the remnants of a Blade of Caliban shattered in battle long ago. The Halberd of Caliban incorporate the same grim and now long-lost technologies that power the other weapons of the Deathwing Knights.
