The Shrine of the Eternalith

The High Priest of the Temple of Solaris has unwittingly awakened an ancient power. The eldritch evil has compromised the divine protection on the local burial grounds, and the heroes find themselves in a life-and-death struggle against an undead force that threatens the town of Highpass. As they investigate the Temple and the necrotic-tainted catacombs below, they must rescue trapped clerics, defeat deadly undead creatures, and ultimately confront the source of the malignant force in the Shrine of the Eternalith.

The Shrine of the Eternalith is an approximately 15-hour D&D 5e adventure for four 3rd-level characters.
