Crathygtan

The Crathygtan, also referred to as the C'tan, are a rumored Alien species, connected with The Phantom Empire. It is believed they were once competitors with the Daam K'Vosh, and may have become the dominant species in the Galaxy following their disappearance. However, it is believed they are currently in decline, if not already extinct as of 817 A.S.

To most of the population of Sirius, all outside the Phantoms, they are unknown.
