From publisher blurb: For a level 17 party! In the vast emptiness of the Astral Plane, a bell is ringing. Ding! Demons are beckoned with its call. Dong! Angels rise with its chorus. Ding! Its song spells ruin and woe. Dong! The fate of worlds hang in the balance! Somewhere on the Astral Plane, the Bell of Eternity is ringing. This mysterious relic of a forgotten age brings the ruin of whichever world it finishes its song upon. The forces of both angels and demons are vying for its control, and success for either faction spells doom for the PCs! The party must claim the Bell on their own, caught in a battle between fiends and celestials in the Astral Plane! For Whom the Bell Tolls includes PLAYER SAFE MAPS - maps you can show your players for each encounter area that does not reveal important details like the locations of traps, treasure, or hostile creatures.
