The Adventure Zone

The wildly bonkers adventure from the hit podcast of the same. The Adventure Zone is heavily story based with about eight different arcs, each one quite different from the last.
The first Arc gives an alternate ending to the Lost Mine of Phandelver adventure, which transitions into getting the players hired by a secret organization whose job is destroy incredibly powerful, and evil, magical artifacts. Then into your first job for them.
The rest of the arcs are the players working for this organization, and discovering secrets along the way. Secrets of the setting, the organization, and themselves.
