From the back of the adventure:
Under the Dark CanopyPowers in Loudwater are searching for the reasons behind the orc migrations. But expeditions into the vast High Forest will uncover more than just the movements or orcs. Dark things move in the forest, searching for egress.
Dark Exodus is an adventure for Dungeons & Dragons (3.5 Edition). It can either be played as a stand-alone adventure, or as part of LGR - Legacy of the Green Regent campaign offered by the RPGA. Designed to challenge 3rd-level heroes, in this adventure they face the strange dangers that dwell in the great expanse of the High Forest.
To use this adventure, a Dungeon Master also needs the Player's Handbook (D&D 3.5e), the Dungeon Master's Guide (D&D 3.5e) and the Monster Manual (D&D 3.5e). This adventure is set in Forgotten Realms, and it may also be useful, but not necessary, to also have a copy of the Forgotten Realms Campaign Setting.
The scenario was distributed with a multi-page pull-out illustrations and handout section.
