Pah-wraith

The Pah-wraiths are non-corporeal beings once native to the Bajoran wormhole. According to Bajoran texts, at some point millennia ago, the Pah-wraiths became enemies of the Prophets, and were allegedly banished from the wormhole to the Fire Caves on Bajor. Bajoran texts also record the Pah-wraiths as being "false Prophets". (DS9 episodes: "The Assignment" and "The Reckoning").
