Mysteries of the Pillar of Blue Light

From publisher blurb: AN ADVENTURE by Morten Greis FOR Odysseys & Overlords SUITABLE FOR 4-6 CHARACTERS OF 5TH – 8TH LEVEL Gods have died and their names are forgotten, but traditions live on. Though pilgrims and worshippers may have forgotten why, they perform certain rites or visit places, that otherwise have long been abandoned. One such place is the remnants of a temple kept in use by a cult of wererats, who performs pilgrimages to the site to worship their ancestors. Whatever gods they once worshipped here, has been forgotten, and only the worship of ancestors remains. This adventure takes the player characters to a mysterious underground temple, which hosts strange powers and memories of the past, and though wererats claim to worship their ancestors here, other powers are at play as well, and the adventurers may accidentally bring back a powerful force from the past.
