Death stalks the Isles!
All through the Known World, the stories are told again and again, by pirate captains and boasting merchant lords: a ferocious sea monster is stalking the trade lanes, and no vessel is safe. The call goes out for a band of heroes willing to dare the impossible: to slay a leviathan of the murky deeps.
Are you and your companions the heroes that can bring back the head of the sea dragon? Or will you perish like those before you, adrift on the unforgiving sea? An adventure of exploration, courage and cunning, Isle of the Sea Drake will challenge characters with savage natives, the walking dead, gold-crazed pirates, a sea dragon, and an ancient mystery from beyond the stars.
When heroes dare the sea dragon, only the most courageous will survive!
Isle of the Sea Drake includes a full-color double-sided poster map depicting the area of the adventure. This world-neutral adventure can be used alone or to launch a campaign in the epic fantasy world of Áereth.
