The way gets rough, and the ceiling lowers in front of the adventurers as
they push on past dark corners and foul-smelling passages. They duck
their heads down to get through a narrow doorway, and when they pass
through, they see....nothing. It's black as pitch.

If an adventurer re-lights his torch and peers ahead into the gloom or
has dark vision spell/ability, he will be able to just make out the silhouette
of someone with his arms held up over his head. The adventurers had
better keep their eyes open wide if they approach the man. He doesn't
move. This is no man...it is the shrivelled corpse of a long-dead orc,
wrapped tightly in thick webs. They've stumbled into the lair of one or
more giant spiders . The adventurers may forge ahead into the dank
cavern if they dare….
