The duchy of Aster Malik was a tiny province of the Seleucarian Empire, located to the north of Seleucar on the Asterian Peninsula. It is best known as the homeland of the infamous Duchess Castomira Brangwin, unwitting thrall of her Tsol'teth blood in the Wars of Succession. The island of Kanjera was located off the coast of the duchy before its collapse.
In modern times, only Aster Keep remains.
