Teer Village
** SPOILER **
STEP 1: Drop bones onto the dais (the square between the two purple squares, to the south of Wilfurd's portrait. Yeah, not the best looking dais, but ACS has limits on the number of objects which can be defined.)
STEP 2: Walk over Wilfurd's portrait to create a water flask.
WARNING: ACS has a limit on how many tiles may exist in a region, and the temple is near its max. If the water flask is not generated, you can try removing any stray objects you may have left sitting around in the various rooms.
-OR- : Clerics and druids may skip this puzzle by simply using their spells to aquire water.
