The Deep Dark

A bat embryo

"True delvers know of the Deep Dark. The one where your torches barely light up your hand, and even a lantern is nothing but the glow of a firefly's ass.

"It lurks, lies in wait like a living thing, in the corners of forgotten ruins, in ancient woods and caves below the earth, all the places where the sun has never shone.

"There are things that thrive in that dark. Pale, blind things that are born, live and die in shadow. Though they fear the light, the Deep Dark is their realm ...

".. and they are hungry."
