Petrified Adventurer's gather no XP

The party picks up the trail of the lost adventurers. They follow the trail to another town and find a library that has been abandoned. As they look into the library they find a hidden box with an evil magic book and some holy texts of Lathander.

A medusa has been masquerading as a cleric of Lathander and luring people out to the old temple to petrify them. She planned to use them in a ritual in making a stone golem. The party fights and defeats here and her horde of gorgons.

They find and heal the adventurers and loot the temple. They find a book that none of them can read. It was a Manual of the golems, but they ignored it. So they left it at the temple.
