Morgheim

At the heart of the Marshes of Madness lies the Necropolis known as Morgheim. Once the capital of the Strigoi, Mourkain was founded by Kadon shortly after he fell under the dominion of the Crown of Sorcery. At one point the Strigoi realm reached to the Black Gulf, all control from Mourkain. The Orcs were far from happy at being pushed from the ancestral lands and joined together in a great Waaagh! Led by Warboss Garsnag Craktoof, Mourkain was sacked, and the power of the Strigoi broken forever. Now known as Morgheim, the city may no longer exert its control across the Badlands but is still a formidable place of lost power.
