A powerful but mad wizard has been experimenting on a local goblin population. He pays the chief well for his co-operation and offers the tribe protection from some of their more powerful enemies. Over the last decade the tribe has relocated behind his walls and he has, through the use of demonic allies, bred several half-fiends from goblins and worg. The first
have come to maturity and more than a dozen more are maturing. The mage has also imbued the blood of goblins and worg foetuses with the essence of pure evil, breeding a new race of fiendish goblins and worgs to serve him. Several of these horrid creations he has instructed in the magical arts and many others have become skilled wamors. There is now a formidable contingent of monsters in his dark keep and his work continues.
All would be well for this wicked madman if it were not for the reports coming from travellers in the area telling of strange flying beasts. What is worse, the creatures have of late begun to attack travellers, spreading the fear even wider. Clearly something must be done and the players are hired to investigate the stories and the attacks.
