Eternal

Eternals are transcendental beings that have always existed in the Corruption Chaos Universe. They often personify concepts or locations. They exist outside of our Multiverse in a completely different plane, separate from the 'Ephemerals'.

They, along with other beings, are kept in check by the Forces.

Known Eternals
There are currently only five completely known Eternals: Nothing, the personification of the Void; Memoria, the Guardian of Memories; Ouroboros, personification of infinity and endlessness; Lord Mortis, the personification of Death and Entropius, the personification of Chaos. Although, some people may argue that other personifications such as the rumoured consciousness of the Underworld could be Eternals too.

Chronea is a rare example of a Pseudo-Eternal, as her consciousness has become infused with the timestream, shattering her human form, so she represents Time.
