The Vitrified Village

From publisher blurb:

A fantastic alien ruin seemingly made of glass is the site of a fateful encounter on the planet Ashe. A local cult has taken over the ruins in order to worship the site’s enigmatic builders and to initiate their expected Grand Communion — the joining of the adherents and the idols of their worship. But when the PCs are hired by the ruins’ caretaker to investigate what the sect is actually doing, the heroes come face-to-face with the planet’s past and its destiny. Either might spell the abrupt end of their adventures.

The Vitrified Village is a short science fiction adventure using the Cepheus Engine, Cepheus Deluxe, and the Original Science Fiction Roleplaying Game rules. Other 2D6 systems are easily adapted.
