The Nature of Water Summoning (NWN)

This note appears to have been left by Cyril, the mage who created this dungeon.

As I suspected, there are a number of natural pools in these underground chambers that can easily be converted into summoning cisterns. Once I have completed construction of my laboratory summoning a powerful elemental to do my bidding should simply require the addition of a Slaadi Tongue to the pool, along with the casting of Melf's Acid Arrow.
