Riduvian Barrows (building)
The Riduvian Barrows are the resting place of the Kartharaddi Magi-Imperators. The Barrows contain dozens of ancient hollow hills, which Magi have turned into massive hives of ancient tombs and graves. Each hill is built from the inside to contain incredibly intricate resting sites for important and respected Magi from across the Imperium, often decorated with magic to show off the commissioner's powers.
The personal guard of the imperator stands ready here, prepared for any eventuality and constant attempts by necromancers and adventurers to raid the site for subjects and riches.
