Trask (The Highlanders)

Trask was an individual who represented the Celestis' interests at an auction for the Relic in the ReVit Zone on Earth during the late 21st century. When he attended the auction he was dead, re-animated by the Celestis in order to attend the auction. Upon seeing the Doctor, Trask remembered that it was the Doctor who killed him via drowning, though the Shift later admitted that it had altered Trask's own memory to be more "dramatic."

Trask made a deal with Qixotl following inconclusive end of the auction's proceedings to take the Relic back to Mictlan. (EDA: Alien Bodies)


 * Trask might be the same Trask from The Highlanders, who also met the Doctor and (possibly) died by drowning, but this is never directly stated.
