Etymology: sommar solstånd means summer solstice in Swedish, which comes from the name of Queen Solstice in Kaeva. Summer is also related to her being the Summer Season (water).
Summer is a member of the Wielders, who convinced them to allow her to join because of her name (which is related to the seasons mentioned in the prophecy -- she turned out to be right). She is beautiful, smart, and charming, and does everything for her own gain.
