Ice sprite

The Ice Sprites are a race of humanoids who inhabit the Land of Snow, a plane different from Gielenor. The only known members of this race are the Queen of Snow and her son, Prince Jack Frost. Ice Sprites seem to generally have pale blue skin and blue hair, and possibly possess some powers over snow and water. At least Jack Frost has direct access to these magics, and the Queen herself is charged with bringing snow to Runescape during Christmas time.
