From the description:
While the adventurers are calmly moving throughout town, they get approached by a particularly weird-looking, young man. He looks incredibly rich, dressed in expansive robes and plenty of golden jewelry matching the attire. His beautiful blue eyes and long blond hair would make for an incredibly beautiful face, and yet he looks very sleepless and stressed. He asks them if they are adventurers and mentions that he is DEEPLY in need of help.
Someone had the smart idea of selling their soul for power, and no way of getting it back. You'll travel through earth to reach the gates of hell, before fighting the hordes of hell, and facing vicious foes that won't hesitate to try and rip your soul apart. Will you save the innocent ? Will you die heroically ? Or will you side with hell?
Soul Devourer is a descent into hell adventure designed for 3-6 level 18 characters for use with the 5th Edition ruleset.
