The Tower at Charm was the name of the fortress created by The Lady after her liberation from the Barrowland. It served both as a palace and the administrative center of her Empire. It was in the shape of a cube, and was constructed of massive, imported basalt billets. The basalt that was not used in the construction of the Tower was strewn outward for a mile in every direction except for a single, perfectly manicured approach, restricting all land access to a tightly-controlled point. The land outside the jagged basalt "moat" was actually beautiful pasture.
