Byss

Appearance
Byss like stated before don't have a defined look and can look like anything they want but a form they all agreed on was that when not shape shifting they will look like a Humanoid silhouette with but replace the black with space.

Biology
Not much is known about Byss biology because of their shapeshifting nature but the only thing that is truly known is that they are so advanced that they get their nutrience from absorbing star light.

Language
The Byss know every language period.

Current State
The Byss have taken over a large part of the Milky Way and seem to almost always win battles with exceptions like when the Byss attempted to invade Mars and enslave the Martians but failed horribly.
