Gravespace

"'Gravespace is nothing to be toyed with. It simply tolerates our presence, nothing more. Should the favour of 'He who rests' be tipped, we will be ripped asunder atop this ever-changing inferno.'""- Admiral Harvel of Flagship 'Humanity's Respite'"

Explanation
Gravespace is a higher dimension to Realspace, the birthplace of all Charred, and the resting place of The Shattered God. Gravespace also acts as a method of Faster Than Light travel for many factions, including The Human Consortium, and The Resurrectionists.
