Waterwall

This unique site is a subterranean base for Iuz's forces creeping west to infiltrate the Vesve far beyond Iuz's own lands. It is virtually undetectable until one is almost on top of it. Hidden by hallucinatory terrain, the entrance to Waterwall appears as a simple overgrown copse. The magic disguises a rocky rift which leads 200 feet down a virtually sheer cleft to a network of cave entrances which are carefully guarded by orcs at all times. Iuz's forces descend and ascend within a column of permanent levitation magic some 5 feet in radius which originates from a magical, copper sphere. A mage of level 7+ is required to activate the sphere and direct the levitation effect. Sometimes for sport, the orcs force their goblin lackeys to clamber down on vine ropes, which means that 400 feet down at the bottom of the rift, there is a fair-sized pile of goblin bones and rusting equipment.

While Waterwall has many networked caverns and passages, its central secret is a magical fountain in a great colonnaded central chamber. The stone fountain is the origin of an extraordinary "standing wall" of water, 20' in radius, which appears entirely motionless. However, if a creature enters the "waterwall," they will feel it flowing, strongly, and, of course, the creature gets wet. There is a 5% chance each day that the fountain's waters can cause ld20 creatures entering it to become semi-invisible for ld6 days afterwards. Creatures so affected appear to be misty and semisubstantial, but can perform actions normally. Give them -2 to AC and +2 to saving throws against spells targeted at the creature. Orc scouts use this magica1 power of unknown origin to aid their spying and skirmishing missions westward.

Waterwall's magic may have similar origins to the waters of Blackthorn within the Gnarley forest (see City of Greyhawk, Gem of the Flanaess book) and Iuz is keenly interested to find out whether more of this magic can be understood by exploring Blackthorn. His Boneshadow spies may already be setting out for the Gnarley, to see what they may learn.
