Blagothkus the cloud giant is still the master of Skyreach, and he has gone to the hall of his cousin Brunvild, ice lord of Uldoveld, for the resources to repair and reoccupy the castle.

A venom maw hydra lair suitable for four or five 10th-level characters. The Red Craw Marsh, so called because of the delicious and plentiful red crayfish that live in the area, is a boon to the nearby village. More than a few intrepid souls brave the swamp each season to collect the crayfish. They either sell the crayfish to local establishments or ship them to nearby cities, where they earn a good price as the crayfish is a delicacy among the wealthy. The villagers have established a tentative peace with a clan of trollkin that inhabit the swamp. The crayfish collectors pay a small fee to the trollkin, who allow them to ply their trade in the marsh without (much) interference. It is a tense but profitable relationship for all involved. A powerful creature has moved into the marsh, however, threatening the delicate balance. When a venom maw hydra decided to move to the area of the marsh between the human and trollkin villages, it brought along a number of creatures that worship and serve it. This hydra and its allies have killed some of the crayfish hunters and some of the trollkin. Each side, unfortunately, believes that the other has broken the truce, thus stirring up animosity and putting both groups on the verge of war.
