Once the two warforged are securely fastened and equipped with the sunrod which will not be be extinguished underwater, they carefully step into the cold water, continuing to walk down the steps. The water itself is quite clear and fresh-tasting, much to everyone's surprise.
The two continue on into the room at the end of the staircase, coming up against a wall which blocks further forward movement. To enter the room you have to walk either around the left or right sides of the wall, which blocks further views of the space beyond. The walls in this room seem to be composed of a tan stone which you have not seen in this cairn before.
OOC: Both of the warforged are now completely underwater but since they do not need to breathe, can still communicate normally, if a bit garbled. They can move at half their normal speed. Once they have moved around the wall I would prefer it if both D20Dazza and Ranger Rick could post using sblock tags; just to keep it a bit more mysterious.
