Seregost

Seregost was a fortress in central-northern Mordor just south of the Ered Lithui, on the Mithram Spur, and was the principle protection of the Mithram Gap. Despite its proximity to Mount Doom, it was bitterly cold and snowbound no matter the season.

It was said that the Black Uruks were bred here, when Sauron first used them to assault Ithilien before the Great Years. It was also the first spawning-place of the Olog-hai.

Seregost is non-canonical, as it does not appear in the works of J.R.R. Tolkien.
