Karst Chantry

From Introduction:

It cost them dearly, but your party of 4-6 starting Risus characters have acquired a map to an ABANDONED Scholomance, a foreboding chantry built in the HOWLING Karst Country west of Sanctuary. The map reveals tantalizing clues to the existence of a legendary OBELISK that bestows wondrous transformations of notentirely dubious nature.

Unbeknownst to the grubby treasure seekers, another team of ne'er-do-wells purchased a similar map. That party was ambushed by the flayed hunters that now lair in these benighted halls and survivors are at this moment being prepared for sacrifice to some unspeakable charnel god.
