The Black Palace was the seat of Detinan power and housed the Detinan monarchs, up to and including King Avram. It was situated in the city of Georgetown. A row of fearsome crosses were placed on the Palace grounds to deter potential traitors with the threat of crucifixion.
During the Detinan Civil War, the Black Palace, and the city it was located in, came under direct attack by Duke Edward of Arlington and his Army of Southern Parthenia, and later by unicorn riders led by Earl Early the Jubilant. Both attacks were completely repulsed by the southrons.
