12.12.7 Mirror Caves

Hidden deep below the northern Vasnari Mountains is a series of twisting
caverns and tunnels made from smooth, mirror-like crystal. The caves are lit by
bioluminescent moss, shedding light in otherwise pitch black corridors, but the
strangest property of the Mirror Caves is the voices and sounds that are
audible, some from many years in the past. 

Keeping to themselves, the peaceful Sileg, humanoid creatures with fungus-like
properties, make their home in the Mirror Caves, staying out of sight in an
effort to avoid potential danger, including the deadly jade spiders that weave
their webs within the caverns.
