Arctic circle

The arctic circle was a druid circle associated with the cold climate where glaciers formed and winters were harsh. Druids who took up the cause of nature in such a climate 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).
