From the Introduction: Illusions and Elusions is a standalone encounter designed for five characters between levels 8 to 10. The Halls of Glass, a mysterious academy for powerful illusionists, holds many secrets found in—and outside of—reality. Its corridors are lined with mirrors, magic, and tricks, all waiting for those curious enough to try and unravel the layers of deception found in each mirage, apparition, and trick of the mind. As its masters would warn: be on your guard, for seeming means nothing - and nothing is as it seems.
