NecroCosm

In a universe there are a limited number of garden worlds - places where life can naturally evolve. Once exhausted and turned into Chars the universe is considered on its way to becoming a NecroCosm. Life may still be present but the building blacks for life are reduced. Life may be sustainable for millennia, even eons or kalpas. (See Time)

There may still be entities trapped within NecroCosms - indeed this is a unifying piece of work to keep the Devourers trapped within NecroCosms until the entire reality can be finalised.
