Publisher's blurb:
"Angus and Oswald are two wizards trying to unravel the mysteries of the many planes of existence. To achieve this, they often hire groups of adventurers to risk their lives in the pursuit of knowledge (and of course, treasure). In Edge of Darkness, Angus and Oswald hire a group of adventurers to investigate the possibility of a permanent portal to the Shadowfell in a nearby ruined temple, and to discover what lies beyond it. The group will explore the ruins, find the portal, unlock the secret to activate it, and step through to the Shadowfell. If they want to return home however, they might have to enlist the help of a local, or risk being trapped there forever."
