You are at a 4-way intersection. There is a large, irregular central chamber and four tunnels lead away from it. A good deal of broken stone is on the floor, as if miners sometimes come and chip away at the walls. There are smudges beside the four tunnels that look vaguely like different symbols. The one that goes back to the mine entrance looks like a tree. There is also a rough square, a triangle, and a circle.

[Since this crossroads leads to everything, the Goblins usually watch it all the time. There is a 50% chance that Goblins will attack any intruders here. Flip a coin.
