Write a detailed description of a spooky crypt with molding, mainmast, candles, and an arch.

Affixed to the walls at regular intervals, brackets hold partially burnt candles that provide a dubious light. The connection between this hold and the world above grows thinner as the massive mainmast blocks the meager light from the grating. A wide arch, its molding chewed and missing chunks, opens like a gaping maw into a black hole whose size can be sensed from the change in temperature near the entrance.
