Tammeraut's Fate
Ten years ago, zombies arose from the foamy sea to take vengeance against the inhabitants of Firewatch Island. Now, they have risen again, just in time to welcome the visiting player characters! Will your heroes manage to escape the island with their lives (to say nothing of their delicious brains)?
The PCs have to clear the island and learn its secrets, then defend it against an undead attack and then travel to the bottom of the ocean to seal Dagon's Maw!
Pgs. 19-50
