An elemental wizard with crystalline growths on his skin, standing in a chamber where four distinct environments meet at impossible angles - a roaring hearth with flames that cast no heat, a waterfall flowing upwards along one wall, a whirlwind frozen in time, and a garden of crystal flowers growing from stone, all separated by perfect straight lines yet somehow occupying the same space, geometric shadows that don't match their sources, stained glass windows showing scenes from impossible perspectives
