Orbis

Orbis was a planet to which the Eighth Doctor was teleported by the Sisterhood of Karn following his encounter with Morbius.

History
Orbis was inhabited by the Keltan race. However their settlements on Orbis were, over the course of 600 years, frequently destroyed by the presence in close orbit of a remote stellar manipulator that took on the appearance of a moon. (BFA: Orbis)
