The interior of the castle was much less hideous than the exterior, though it still had that same, crystalline appearance. Unlike the jagged, uneven exterior, it was all flat floors, evenly spaced walls, smooth columns, and elegant doorways. The same colour scheme pervaded throughout: all soft purples, blues, and light reds, with the more stark colours provided by the non-crystalline furnishes and fixtures. Strangely, he couldn't pick out a light source within the corridors he was led down, as if the structure itself provided its own luminescence. However, looking up, he could barely see the high ceiling in some parts, so thick was the darkness above them. It was all very strange, but he felt no sense of apprehension from the fact.
