Orb of Winter

The Orb of Winter is a magical orb that is rumored to be one of powerful ancient artifacts that creates a zone of cold in a large diameter around the orb and changes the weather patterns when activated. Conditions in two places in the world are attributed to the orb, The Frostlands in Arcadia, and Devouring Marsh in Solum.
