The Black Cube
Artefact of Doom
The Black Cube is a small cubical device constructed from an unadorned, apparently indestructible matte-black material.
Whenever the artefact comes into contact with blood runes of chaos will appear on its surface in a blazing red.
According to legends the Black Cubes were ancient devices of unfathomable power created by some of the first Chaos Champions as weapons of utter destruction. Each of these mysterious devices is said to require “Spilling the Ocean Blood of a Kinship” to activate and its effect are said to “Consume the world in the Black Dawn”
No black cube has been used since the time of the Great Crusade where one presumably destroyed an entire world, including half an Imperial Army Expedition Fleet, everyone on the planet and a third of a Titan Legion.
