Galadina

 was a Warpsmith of Phaidon and an outsider at the Time Lord Academy. She spent most of her time with Taylor Addison (a human), Neeloc (a Time Lord) and B'arech (a Monan). (AUDIO: Insurgency)

When Antimon was commentating at the Academy about the student unrest, Galadin protested at what he was saying. She was killed in an explosion at the Academy shortly afterwards. (AUDIO: Imperiatrix)
