The Underdark circle was a druid circle associated with life underground in the vast caverns and passages of the Underdark. Druids who took up the cause of nature in such a region had an affinity for this circle and the suite of spells that came to them without cost (they could cast them at any time without having to prepare them in advance).[1]
