Trion (planet)

Trion was the home planet of the humanoid Trions.

Some years prior to 1984, Trion suffered a civil war. At least some of those on the losing side were exiled rather than killed; Vislor Turlough was among these. Even young children, such as Malkon Turlough, faced exile; it seems to have been applied to rebellious families rather than individual combattants. The exile was lifted by 1984, and exiles were permitted to return. (DW: Planet of Fire)

At some point in its history, it was attacked by Tractators. (DW: Frontios)

The Tenth Doctor and Emily Winter visited Trion to make sure that Turlough didn't write the diary that the Advocate was using to manipulate Matthew Finnegan. (IDW: Final Sacrifice)

According to Vislor Turlough, the trees on Trion were three times as high as those on Earth. (BFA: Loups-Garoux)
