A planet largely hostile to the Federation, home to a cult that reveres the Vezda as gods, where the third-season finale of Strange New Worlds, New Life and New Civilizations, takes place.
Skygowan is a non-aligned world that trades with the Orions and has little love for the Federation. Its main city is built around the belief that the Vezda were gods, and the High Chambers of its priesthood float above the streets. Roger Korby is there studying the culture when the events of New Life and New Civilizations begin.
The Vezda that escaped from Vadia IX, wearing the body of Ensign Gamble, comes to Skygowan and starts preparing its worshippers to serve as hosts for its imprisoned kin. A ley line connects the planet to the prison through inter-dimensional space.
A disguised landing party gets Korby out, and two starships fire together to produce the power needed to open the portal. Pike and Marie Batel go through, and Batel becomes the Beholder who seals the prison, freeing Skygowan's people.
