Voidspawn

The Voidspawn is a space-borne organism similar to that of the ether drake, possibly a sub species of the leviathan like creature.

Little is known about the Voidspawn life cycle. Most races who encounter them normally see them as a unhatched unhatched egg or at a very young age. When a Voidspawn egg is layed, the egg is shaped similar to that of a planet. This "planet" eventually forms its own atmosphere and life on it surface, completely duping any race exploring its surface. After what seems like thousand or hundred of thousands of years waiting, the Voidspawn hatches. Its arrival to the outside universe is met with a violent destruction of its eggshell, destroying any life that may have lived on it, sentient or not.
