Biography
Like all Time Lords, Andro was taken from his family at the age of eight for the selection process in the Drylands. Staring into the Untempered Schism as part of a Time Lord initiation rite, Andro was inspired by what he saw in the Schism. (PROSE: A Brief History of Time Lords)

Andro and Fabian were working in their repair shop when an alarm sounded as the First Doctor stole a TARDIS from the repair shop. (TV: The Name of the Doctor)
