Subterranean spider

Subterranean spiders were spiders that dwelt underground.

Varieties

 * Hairy spider : A vicious spider that tended to swarm on attackers.

Locations
Subterranean spiders were particularly common in drow areas of the Underdark, where they dwelt in relative safety due to many drow's reverence for spiders.
