Tirana's Lair, Part 12 (Desnus (V) 9th, 4709 AR)

The Vanishing Stones. The floor of this large natural cavern is composed of two rocky shelves separated by a subterranean stream that flows gently from north to south. The passage into this room opens onto the western shelf, which is bare and flat save for three stone outcroppings. These stones are several feet high and so smooth as to be shiny, twisted into strangely organic bulbs and swirls that make them look like solidified liquid. On the eastern side of the shelf, an arch of stone spanning the stream leads up to the second shelf, which rises an extra five feet above the stream. Unlike the rest of the area, this arch has obviously been worked, crafted into a set of beautiful stone stairs. A low hum fills the chamber.

Entering this area, the heroes can see Tirana conducting her ritual on the higher shelf, and vice versa. Tirana ignored them for the time being, concentrating on completing her ritual.

The three stones in this room are a thaumaturgic anomaly. These stones create a magical effect. This causes any spell or spell-like ability cast on the west half of this chamber to fail, its power drawn into the stones. An impassible barrier is also located directly over the stream, similar to an invisible wall of pure force.

In addition to the hazard created by the stones, three earth elementals guarded this room, under the command of a kobold. The three were summoned by the kobold, attacking the heroes and fighting until they were killed. The kobold hid in a crevasse in the back wall throughout the combat and avoided conflict. The heroes killed it anyway.
