Heavenfall Blade

The Heavenfall Blades are master-crafted Power Swords wielded by the highest-ranking members of the Dark Angels Chapter of Space Marines. According to Chapter lore, the Heavenfall Blades were cut from a single block of obsidian that formed the core of a meteorite that struck The Rock, the Chapter's mobile Fortress-Monastery, in orbit around the Feral Worlds of Al Baradad, shortly after the fall of Caliban. Each of these blades is carried by a master and is as potent a symbol of his rank as it is deadly.

It is said that a small portion of the meteoric substance was dispatched to each of the Dark Angels' Successor Chapters so that the senior members of the Unforgiven's own Inner Circles would also bear the same heritage forged in steel as those borne by the Masters of the Dark Angels.

Known Heavenfall Blades

 * Sword of Secrets - The Sword of Secrets is the mightiest of the Heavenfall Blades, and is wielded by Azrael, the current Supreme Grand Master of the Dark Angels. Its blade is so incredibly well-crafted that it has not chipped nor lost its razor-sharp edge over its many millennia of bloody use. Only the Supreme Grand Master knows that it is also the only device that allows access to the deepest known dungeon in The Rock. Fitting the blade into a cleft in the wall unlocks the iron gate leading to a dark tunnel and the rune-protected cell in which the Arch-Heretic Luther is imprisoned.
 * Sword of Silence - The Sword of Silence is wielded by Belial, the Grand Master of Deathwing. The sword seems to swallow nearby light and sound, absorbing them into its glowing obsidian blade.
 * Raven Sword - The Raven Sword is traditionally the weapon of the Grand Master of Ravenwing, hence its name. It is wielded by Sammael, the current Grand Master.
 * Fellbane - The Fellbane is currently wielded by Balthasar, Master of the 5th Company.
