Tar-Modowk

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

Biology
The Tar-Modowk evolved from the Meg-bania and were especially drawn to temporal anomalies. They were roughly humanoid and were much larger than humans. The Eighth Doctor's companion Lucie Miller described the Tar-Modowk leader as "a bulking, great thing." (AUDIO: No More Lies)

Transport
The Tar-Modowk rode Vortisaurs through the Time Vortex. (AUDIO: No More Lies)

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