The Red Keep
Made from basmuth, most commonly called redstone, the Red Keep was constructed sometime between 4300 DA and 4400 DA. It is located on the eastern edge of The Cruel Wood in the Tritos Dominion. Legend connects the keep to the Sovereign Sage Maltavoris, often referring to dark deeds done inside.
There is a moat with a drawbridge, arrow slits, fifteen foot tall walls, and unmanned parapets. Heavy magical defensives remain active on the structure. The keep is said to be connected to an ancient underground city, which can only be accessed via a secret entrance hidden somewhere within.
