The '''Heavenfall Blades''' are [[master-crafted weapon|master-crafted]] [[powered weapon|power swords]] wielded by the highest-ranked members of the [[Dark Angels]] [[Chapter]]. The weapons were crafted using a single block of jet-black obsidian; according to Chapter lore, the block had formed the core of a meteorite that struck [[the Rock]], the Dark Angels' mobile fortress-monastery, in orbit around the feral worlds of Al Baradad.^{1 p.431a}

The mightiest of these blades is the [[Sword of Secrets]], wielded by the Supreme Grand Master of the Chapter (currently [[Azrael|Commander Azrael]]).^{1 p.461b} Small portions of the meteoric obsidian were also used to craft the [[Sword of Silence]], wielded by the Master of the [[Deathwing]] (currently Master [[Belial]]),^{1 p.421c} and the [[Raven Sword]], wielded by the Master of the [[Ravenwing]] (currently Master [[Sammael]]).^{1 p.441d} It is said that some of the obsidian was sent to the other [[Unforgiven]] Chapters, so that their highest leaders may wield weapons crafted from this substance.^{1 p.431a}
