Fyrax
From Tardis Wiki, the free Doctor Who reference
Fyrax was the commander of the Time Tank which collided with the Doctor's TARDIS. He explained to Romana II that he was on a mission to Aoris' past. He then took the Fourth Doctor to Drang. He was tasked with taking the Doctor to Era 14 as an ambassador. (AUDIO: The Paradox Planet)
He was interrogated as a way to convince the Doctor to help Embery. At the end of the war, he remained in Era 14 and spread the word of Machina with Tyrus. (AUDIO: Legacy of Death)
