Desert circle

The desert circle was a druid circle associated with the seemingly barren wastes that held surprising varieties of life. 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).
