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 Zimmerman's Meg-bania ship in the time vortex and tried to claim it for themselves. (AUDIO: No More Lies)
