The Black Oaks

Publisher's blurb:

This adventure is nonlinear and thus does not have a set map that heroes need to trek through from A to Z. Rather, this is a magical forest that requires consecutive survival checks to gain enough knowledge (The Trek points) to find their way through the forest. The forest has a constant supply of dangers, and sometimes heroes may find themselves back where they came from. The forest contains a pair of giant wolf brothers that stalk the woods hunting anyone that enters.

This adventure plays out differently each time you play it as there is a lot based on random tables.
