Brachinnen

 was a human from the colony Dephys 49. For tax reasons he chose to dwell in the Time Vortex for a year in a specially constructed hotel.

However, the controls of the hotel had been sabotaged, leading to the time winds leaking into the hotel. As a time sensitive, Brachinnen was the only one who could detect the time shifts that occurred. He wanted the Second Doctor to take him away, but the Doctor refused. (PROSE: Vortex of Fear)
