The Naghai Keep was an ancient castle in Korto City on Bajor. The Naghai Keep was the ancestral home of Jas Holza and was the seat of government for Korto and the surrounding area. The keep had a renowned library and many works of art. The walls of the keep were made of fusionstone.
In 2318, Jas Holza invited Danig Kell and the crew of the Kornaire to the Naghai Keep when the Bajorans made official first contact with the Cardassians. Skrain Dukat was among Kell's crew to be invited to a dinner reception at the Naghai Keep and was greatly impressed by it. In 2328, Bennek sought refuge in the Naghai Keep from Gar Osen. Gar had actually been killed by Pasir Letin, who had been surgically altered by the Obsidian Order to resemble Gar. (ST - Terok Nor novel: Day of the Vipers)
