This serves as the first adventure for the four Elven heroes who must eventually sneak into the Shadowfell on a secret operation. The first four missions are not in the Shadowfell. They are designed as missions to retrieve four magic items that each Elf will find beneficial on their future missions inside the Shadowfell.
This first mission utilizes Dyson Logos’ map and background called “Wygralak’s Hole”.
