The home of House Deneith, Sentinel Tower dominates Karrlakton’s skyline. The enormous fortress serves all sorts of functions and contains everything from meeting rooms to training courtyards to smithies and even taverns. It’s also the home base of the Sentinel Marshals, an elite group of mercenary law enforcement specialists that tracks down international criminals. The majority of the city’s economic activity is tied to Sentinel Tower—feeding, clothing, arming, and entertaining the mercenaries constitute an enormous body of work.

Karrlakton is home to the Sentinel Tower, a mighty fortress at the city’s center. The Tower is the headquarters enclave of House Deneith. Deneith families often send young heirs to be fostered here as children, creating a connection that lasts the rest of their lives. The Tower is the headquarters for all Sentinel Marshals, who return whenever their assignments permit.

Older than Karrnath itself, the ancient keep known as Sentinel Tower is the main enclave of House Deneith, the headquarters of the Sentinel Marshals, and a fortress charged with repulsing periodic monster attacks from the Mournland, just across the river. Its history is rich; Karrn the Conqueror commissioned the first of his generals atop Sentinel Tower. The keep is a confusing maze of fortifications, since its defenses have been renovated and augmented numerous times.

Sentinel Tower is an ancient keep, reputedly older than Karrnath itself. It has undergone extensive expansion over the years, both for defensive purposes and to accommodate growth within the house. Even at its current size, Sentinel Tower cannot contain Deneith’s entire complement of house members and hirelings. As a result, Karrlakton is filled with training areas, barracks, weaponsmiths, armorers, and taverns to serve the needs of the tower.
