Publisher's blurb:
Vecna: Nest of the Eldritch Eye is a single-session adventure for 3rd-level characters that takes two to three hours to play through.
The adventure begins with the heroes being hired to patrol the troubled streets of Neverwinter, a prominent city on the Sword Coast of the Forgotten Realms. During their patrol, they discover a mysterious desiccated eye at the scene of a murder. This discovery sets off a series of events that take players through the sewers and catacombs beneath Neverwinter, where they will face off against the cult of Vecna.
As the party contends with the zealots who worship the god-lich, they will learn more about the mysterious eye they found and may even get an insight into the ritual the Whispered One plans to enact in Vecna: Eve of Ruin.
