Volstrom

 was the Acting Castellan on Gallifrey.

He tried to make sense of distortions in the Matrix. He reported to the High Council about Padrac's matrix projections and Padrac's current mission. He mentioned the possibility of a Time War. He presented to the High Council a matrix projection of the destruction of Earth. After Jerastra was killed, Padrac promoted him to Chancellor. He worked for Ollistra. He was shot by the Eleven with a staser modified to allow for regeneration as a means of torture. (AUDIO: Songs of Love) In quick succession, Volstrom was forced to regenerate at least four times, first to female form then back to male then female again. (AUDIO: The Side of the Angels)
