D24.181 Altar Chamber of Storm
A spherical room made of adamantium alloy 700ft in diameter. A tiny pebble floats at the centre of the room emitting a bright gray light. Access within is given by a large 50ft wide bridge that leads to 300ft towards the centre. The room is filled with a raging storm, with arcing lightining that randomly strikes a part of the bridge every 30ft travelled by moving creatures. At the last 50ft, 3d6 storm elementals manifest to attack approaching creatures. A lectern sits at the end of the bridge carrying a smooth stone tablet, the contents of which have long been weathered by the violent storm. The central pebble may be approached using levitation, at which point another 2 greater storm elementals manifest to attack approaching creatures. A special bag made of adamantine threads has to be used to collect this pebble of storm, which, when collected, causes the storm in the room to subside.
