Our heroes have waded through Dungeon, Battlements, Keep, and Court, and now they climb to the very highest pinnacle of Tour Toriel: the stone spire, convergence of ley lines, ancient holy site, and nexus of arcane energies.  The glowering purple tear in the sky floats here, just out of reach, and just about to end the world.

...unless our heroes do something about it.

The Shattered Spire above Tour Toriel is a full-featured adventure with action sequences, dramatic intrigue, and unthinkable horrors.  The adventure can be played in one epic session (4-6 hours) or easily divided into two to four shorter sessions.
