Basalt walls have been carved out of a natural magma tube, forming a neat
circle of a tunnel.  The tunnel has an incline of fifteen degrees or so,
making it a tough slog either upward or downward, yet not so much so as to
warrant a ladder.  Every thirty feet or so, prayers to Asvin, Theoorn and
Osvin are carved in the walls, pleading for help, food, light and,
eventually, death.
