Tawntoom Citadel
this was the vast fortress built inside the cone of a huge, inactive volcano on the planet Roon by Governor Koong. Also known as the Frozen Fortress, it was located in the area known as the Tawntoom Province. Unknown to Koong and his minions, the site on which the Citadel was built was one of Roon's greatest sources of Roonstones. When Imperial Admiral Screed reneged on a deal, Koong flew into a rage and fired his weapons on the Citadel, in an effort to trap Screed inside and kill him. Screed managed to escape, however, leaving Koong with nothing but a pile of rubble. The remains of the Citadel were later chosen as the governmental facility used by the Council of Confederated Provinces.
