Garrison, Montana

The investigators arrive in the remote mining town of Garrison, Montana, seeking answers at the isolated Tuesday Night Academy observatory. Their investigation quickly plunges them into the wilderness, where a dilapidated ranch and a towering fire watchtower offer sweeping but terrifying views of the surrounding mountains. What begins as a search for astronomical anomalies turns into a fight for survival.

As they delve deeper into the rugged terrain, the group uncovers a hidden ravine choked with thorns, guarding the fetid nest of a sasquatch tribe. Even more disturbing is an irradiated, sealed cavern glowing with a sickly green light. Here, they must confront alien Mi-go creatures scouring the earth for a fabled seed of Azathoth, forcing the investigators to face the cosmic horrors lurking beneath the Montana sky.
