Fort Winterhal is a lightly fortified castle located in the city of Helmira. Officially it is a winter residence for the Kythiran Empire's royal family, the House Viromaro. In reality however, it was designed as a sister palace to Fort Summerhal. Where Summerhal is smaller and more isolated, Winterhal is larger and at a more convenient location. Both castles have a remarkably similar layout, focused around two towers, a large garden with water feature, and a grand hall, with the ground floor being used by a ballroom, and the first floor being used for guestrooms and apartments.
