Tar-Modowk
The Tar-Modowk were a race that fed on time.

Transport
The Tar Modowk rode Vortisaurs through the time vortex. (BFA: No More Lies)
History
Time loops eroded the barriers between the universe and the time vortex, allowing the Tar-Modowk through into the universe. The Tar-Modowk then spent aeons trying to find some trace of their previous existence. The Tar Modowk eventually found Zimmerman's Meg-bania ship in the time vortex and tried to claim it for themselves. (BFA: No More Lies)
