Mandorla

Mandorla was a planet inhabited by the version of Leela who was abandoned by Romana III on Legion. The natives were peaceful, but Leela helped them defeat a Sycorax invasion, so they gave her a house. Irving Braxiatel identified Mandorla as the site of the paradox destabilising the Eye of Harmony, and when Romana II went there to investigate, she met with Leela, but it began to rain stones as the Watchmaker arrived.
