Sitting on the rocky cliffside shore of Catspaw Lake, Bolukbasti Grotto is a twisting set of caves reached by stairs up the steep shores – stairs that have decayed and fallen to the erosion of the lakeshore. Exploring past the great cat den near the entrance to the caves, the main grotto (the long east-west cavern) has a ceiling height between 30 and 160 feet and a number of side caves and galleries, especially among the twisting smaller caves north of the main grotto.
Approaching the western end of the grotto, there are a pair of stone bridges that span over it about 20 feet above the grotto floor (if using 10′ squares). Further construction overlooks the grotto as we continue deeper westwards, as well as a sealed door into these areas on the south side of the cave. At one time the constructed areas were used by a court of shallow dwelling gnomes, but since then it has been home to a cult, bandits, and most recently as the staging area for an incursion of Githyanki seeking a lost silver sword.
The 1200 dpi versions of the map were drawn at a scale of 300 pixels per square and are 28,800 pixels (96 squares) wide. To use this with a VTT you would need to resize the squares to either 70 pixels (for 5′ squares) or 140 pixels (for the recommended 10 foot squares) – so resizing the image to 6,720 pixels or 13,440 pixels wide, respectively.
