From the introduction:
While many know legends or stories about mythical artefacts granting immortality, the gnomish scholar and archaeologist Ardell Hoyt is certain he’s found one. For many years, he’s been studying dusty tomes and ancient inscriptions, which could lead him to the thing he desires the most: a way to cheat death. He believes there exists a lighthouse on the border between this life and what lies beyond, its light guiding the dead to their final rest. However, should a living soul ever manage to bathe in its divine light, eternal life and wisdom would be granted to it. After all this time, Ardell is certain to have found the path to the afterlife, located underground in the “Cave of Lights”. Together with your party of adventurers, he’s ready to see his life’s work fulfilled.
In this 3- to 4-hour one shot, a party of 3rd to 4th level characters will venture through the Cave of Lights and discover if Ardell Hoyt’s theories are correct. Will they survive the trip through the cave? Could immortality re-ally be within their grasp? Is it safe, to Follow the Lights?
