Sycorax (The End of Time)

A Sycorax was a patron at the Zaggit Zagoo bar on Zog when the Tenth Doctor arranged for Jack Harkness to meet Alonso Frame. (TV: The End of Time)

Historians were aware that Sycorax could be found in disreputable drinking establishments across the cosmos, trying either to hawk their ill-gotten gains or to intimidate someone into buying them a drink. (PROSE: The Monster Vault)
