Enter the Dagon (#95), softback adventure for Dungeon Crawl Classics, by Harley Stroh
“The Isle of Dagon: to common folk, it presages death, pestilence, and woe. To warlocks, witches, and wizards, the isle offers a wealth of occult power, forbidden knowledge, and spells beyond the ken of mortal man. But before you can lay claim to the island’s secrets, first you have to survive its fabled spell duels — a series of death matches where only one caster may reign supreme.
Wizards and elves will be tested to the fullest of their abilities. To triumph, parties must also survive the machinations of the other contenders and their wicked retinues. For when vying for the title of Master of Dagon, and battling against some of the most powerful sorcerers to tread the Known Worlds, you will need every advantage you can glean. Will you and your companions sit passively by, awaiting whatever fate befalls you? Or will you take the fight to your foes?
And when your life — and those of your companions — hangs on the casting of a single spell, will you have the courage to accept Dagon’s challenge?
The time for questioning has passed. Black-sailed ships have come to ferry you and your companions to the fabled death matches. It is time to Enter the Dagon.”
