Parek Tonn was a fortress on ancient Bajor. The fortification was built into the face of Dahkur Province's Mount Kola. In a vision Kira Nerys experienced, she and her Bajora forces planned to enter Parek Tonn, but found it inhabitated by the Eav'oq. The two groups later stood together in the fortress against the Ascendants. (DS9 novel: Warpath)
