Galah

Galah was a female Time Lord who lived a long, tedious life as a Gallifreyan sculptor and pacifist.

She went to the Time Lord Academy with The Doctor. They were never close, due to a difference of opinions regarding the nature of good and evil. Galah believed that goodness was a state of being rather than a process.

At one time, she materialized her TARDIS on an asteroid named Victoria, and created a dreamscape based on Wychborn House by hooking herself up to the protyon unit inside her TARDIS' console. (NA: Strange England)
