Heliodor

Heliodor, the child and guardian of Space and Time

Heliodor was created by Nabul and Laeia together, both as a technical spawn of theirs, and protector who would watch over them during their isolation. 

He inhabits a unique ability that, when combined with his parents, can create these hypercubes called Etherecs, which can be used for multiple things.
Currently, there are less than a handful Etherecs ever created; one of the only physical items that prove the long-forgotten existence of Heliodor and his parental creators.
