>Take the third path and investigate that window!
>You follow the path toward the fused bubbles. The path is curved and slick, making the going slower than you'd like. Periodically you have to slow to an awkward shuffle or hold onto a piece of terrain as the slope becomes too steep to easily balance upon. The air is quiet and still, without any hint of an odor.
>As you crest a blob-like distension of crystal, you reach the spheres. They are arranged in a triangular pattern, fused in the middle. One of the spheres is about half subsumed into the fusion, while the other two are less so, maybe only a fifth of the way or so. They are about the same size, perhaps fifteen feet in diameter. Their surfaces are perfectly smooth, as the whole crystalline mass has been. You cannot see anything like a seam or mar along them, even where the spheres fuse together. The window is nearby, at about chest level to you, shaped like a rough oval and a bit over two feet across. At a glance, from your current position, you cannot see much inside, but you note the spheres seem to be hollow. The walls seem to be about half a foot thick and rounded at the edges of the window.
