Dark Matter Crystal
From Warhammer 40k - Lexicanum
The Dark Matter Crystal, also known as the Umbralefic Crystal,[3] is a powerful Chaos relic that was created by the Cult of Magic cabal after they siphoned the perpetual gloom from the location where Mangel III once existed in realspace.[2] Those who possess the Crystal can use its energy to temporarily fold space, creating a localised wormhole through which they or their allies can step.[1][2]
