Generate for me a description of a magical scene inside a medieval building with candles and niches.

Small niches pepper the main wall, each fitted with a faceted crystal lens encircled by an iron frame. Tiny iron hinges to the left of each lens indicate a method of access to the candles that nestle in the niches. When lit, the glowing image of a riolur leaf casts a sprinkling of rainbows across the floor.
