The Crystals Point the Way

With a start, you realize that the placement of the crystals is not as random as it seems at first glance. There are five distinct colors of crystal, apparently scattered at random, yet all shaped like spearheads. All examples of each color point toward a separate passageway. When you pick up one of the shards, all those of the same color begin to rattle with a slight shaking upon the stone floor where they lie, and the piece in your hand pulls lightly in the direction of the path toward which that color points. You choose a passage and, after gathering the shards which point out that particular tunnel, proceed along your path with caution.
