N'Tia was the planet of the N'Tians.
When the Fifth Doctor and Peri visited N'Tia, they accidentally started a rebellion between the N'Tians and their slave workers. The Doctor and Peri were chased by N'Tian soldiers.
N'Tia had at least four moons. The flower Pilgrim's Lantern could only be found on N'Tia. (PROSE: Light at the End of the Tunnel)
