Citadel's Three-Day Dungeon

It's the dreaded place where the citadel confines the slackers, the wounded, and occasionally those who dare to defy. The chilling moans and groans from the dungeon serve as a constant backdrop to the workers' toil.

Given that the prisoners seem to last no more than three days before being eerily silenced and replaced, it's infamously known as the "Three-Day Dungeon" among the workers.
