You find yourself surrounded by a maze of blue and white crystal walls, impossibly high. Thy sky above churns with magical energy and Screamers of Tzeentch fly around overhead. You are in The Crystal Labyrinth. If you can find The Impossible Fortress and The Hidden Library inside, infinite knowledge will be yours. But first you must navigate the maze, which shifts and changes with reality. You turn your head and where you'd just seen a wall you now see a hallway. Likewise the hallway to your left has disappeared, replaced by a crystal barrier covered with alien red vines.

If you do find your way to The Fortress you must then answer the nine riddles of The Guardian before you may enter. If you fail, you're doomed to wander the maze forever.
