Penguinball's Hibernal Den

Another tunnel leads you away from the wailing of spirits, and you find yourself in a crystal encrusted cave. More researchers were housed here, with a field research tent set up in the middle of the vast crystalline chamber. Dragons measure crystals with strange instruments and take notes on clipboards and you become aware that the crystals, which glow with different colours, all vibrate at slightly different rates, creating an eerie kind of music.
