No businesses are in the Karda. There is a grist mill for the soldiers, but no public amenities. It is a fortress, with barracks for the Flayer Guard and Znir Pact, armories, and other facilities needed to hold the citadel in the face of a siege.
The Keep: The seat of Xorchylic’s power, the Keep is the strangest building in Graywall. The mind flayer took a personal hand in its design, and its walls are whorled and rounded; at times they gleam with an iridescent sheen. Fifty elite troops are garrisoned within the tower, and it is fortified to withstand a siege. Xorchylic’s throne sits on the third floor, and he spends most of his time in this great seat, listening to the thoughts of the town and plotting an incomprehensible revenge against the lords of Xoriat.
The Last Tower: This is the courthouse of Graywall. It is also the last place many of those who come before a magistrate ever see. The tower serves both as a prison and as a center for torture. Droaamish law doesn’t believe in incarceration as a form of rehabilitation, and prisoners are only held if they are waiting for transfer, execution, or serving a sentence in the arena (which can last days or weeks). Public executions are held in the plaza, and statues are also arranged around the tower—these are victims petrified by the medusa magistrate and left as a warning to others. Typically, the justice has the right hand of a petrified victim removed, to ensure that if the victim is restored it is at least maimed.
