Shrieking Marsh
A perilous bog that surrounded the Misty Lake, home of the wizard Malduc.
Arthur’s envoys had to travel through the Shrieking Marsh to find Malduc and enlist his assistance in the rescue of Guinevere from an abductor.
The marsh was also inhabited by Sir Dodinel the Wild. Adventurers crossing the marsh were plagued with quicksand, giant fish, boiling waters, enchanted birds, and an occasional heart-stopping shriek.
