After the arrival of the Watchers in Blood Sands Castle, and the building of the Tower of Sand, as they called their local training tower, things changed in the desert outpost.
No longer were they isolated and rarely visited, the castle was a bustling hub of activity in the desert, with the main gates open every day and a packed market inside the walls, something that was an unthinkable risk when the Castle was built, operated at maximum capacity every day, easily selling out all the available stalls.
Since the location didn't exist before the dungeons, they didn't have to worry about the crazed former occupants traveling here via an unguarded transport circle, so the Blood Sands Castle had become open to the public, under heavy guard by the two Lieutenants who are constantly stationed there.
