From publisher blurb:
The Raspberry Hills seem a mystical place made to inspire artists with its blossoming summer months. People from the neighboring towns and manors make their way here to pick raspberries during the day and celebrate in the evenings. Most would gather at the center of the fields, atop the highest hill where the ruins of an ancient structure sit, its origins long forgotten. But this season abruptly ended. Persistent nightmares thought to originate from the crumbling keep drove the panicked attendees away. The fear and dread grow every day, as if something diabolical is about to unfold.
The Ruins of High Hill is a Q-Crawl, or Quick-Crawl, that can be run for a group of four to six players with 15th-level characters. This crawl would be considered a ‘medium’ to ‘hard’ encounter.
