Glower
From Tardis Wiki, the free Doctor Who reference
Glower was the head technician on Project Alpha, which involved the creation of a timonic fusion device. He worked with Narvin to create the device. He disobeyed the High Council's orders based on Braxiatel's calculations, and detonated the device. This action brought the destruction of Minyos and the start of the Time Lords' non-interference policy. (AUDIO: The Inquiry)
