Relics

”Sure. Why not.” This article is incomplete as it requires input from multiple creators and sources, so feel free to edit it to add your own additions.
Relics are universally indestructible objects who’s functions are essential to the creation and continuation of the narrative, as well as plasma temple and the specific universe it resides in. (however for some relics that are fundamentally tied to multiple universe, this is not the case.)
All relics can not be destroyed, and can only be transferred from one state of being to another, while still maintaining its original purpose. All relics function on the idea of a bootstrap paradox, Meaning they cannot be created, as they themselves are required for their own creation. This is usually accomplished through time travel.
(Note: Even though the Core Controllers are relics by definition, they are more deserving of their own article.)
