Presenting the first sketch of a graviator
Graviators are mysterious, powerful beings that wear hypersuits, armoured space suits made of 4-dimensional objects, known as tesseracts. They can manipulate gravity; curve and bend spacetime as they please. This enables them to move very large and very heavy objects with no effort whatsoever. They use this power to protect inhabited planets caught by the gravity pull of black holes by moving them to safe places. Uninhabited planets they don't care much about, unless they are bored. Then they play a game of Singularity, potting them into the centre of the black hole to pass time.
