The Wall Breakers (Daroo Holybrew, Ulmo, Rude, and Zatamba) enter Freyborough for various personal reasons. They cannot complete what they wish to do because the town has gone non-euclidean. Buildings are upside-down and/or inside-out. Townsfolk cower in their homes and many have left.
The heroes decide they must enter the tower and figure out the problem. Ulmo eventually shatters a crystal in the tower’s lab, and restores time-space to normal.
After un-petrifying Horace, he bids the party go find the adventuring party that sold him his crystal because it was clearly not what he paid them large sums of gold to find. In return, he will give The Wall Breakers a finder’s fee.
The heroes get a description of the party and head out into the town.
