Contemelia

The Contemelia are an alien race of neutral, multiverse-travelling 'observers,' and the original masters of the Anihilaarg.

Appearance
The Contemelia are fifth-dimensional beings whose true forms cannot be perceived by three-dimensional beings. Most three-dimensional beings would instead see a Contemelia as an animate projection of what holds the most emotional sway over them (a living version of the Mr. Smoothy mascot in Ben Tennyson's case, Rook Da in Rook Blonko's case, a duplicate of himself in Maltruant's case), while a genetometaphomorphic lifeform such as Skurd would instead just see a Contemelia as a mass of energy.
