Expedition from the Mysterious Peaks

Expedition from the Mysterious Peaks is an action packed, dual-genre adventure series powered by 5E and inspired by iconic adventure classics.

The adventure unfolds from two different origins. One is as a party of adventurers seeking to stop a mystical threat. The other is as a team of galactic explorers following the source of a generations-old distress beacon.

These characters' destinies collide, intertwining into a rich, versatile campaign series.
