>Hopefully it has an end.
>Investigate the chamber.
>Keeping cautiously optimistic, you proceed onward.
>The tunnel widens a little, then opens up to a vast chamber. Immediately your eyes are drawn upward to a lattice of crystalline stalactites hanging from the ceiling. There are dozens of them, easily hundreds feet overhead, extending downward. As they do, they, branch into more stalactites, which branch into even more. Where the individual stalactites meet, they fuse together to make crystal bridges and platforms. From those, new stalactites extend. They weave together to form an intricate lattice, some parts of it large enough to support a small room, and others near the bottom so tiny that you could easily wrap them in your hands. Somewhere up above, you can see a faint glow, but you cannot make out what the source is. You can sense a gap somewhere up there, as well. As the lattice continues downward, more and more of the stalactites fuse together, until mere feet over the floor the entire mass comes to a single point at the center of the room.
>Below, the floor curves downward, smooth as the sphere that you had entered from. Near the bottom is a pool of clear water, perhaps a knee deep at its lowest point.
