Solaria has granted Fiona her Blessing of Eternal Spring.  Granted the charm and grace Solaria is known for, after coming of age at 16, and appears to have ceased aging.  Barring unforeseen incidents, she should live as long as the Fey and live to guide the Coven for many decades.  She is several years older than her appearance might suggest, and only acknowledges Greta as her senior.

Having Solaria as a Patron very much makes Fiona a 'White Witch'.  She has a strong sense of community and believes that the Coven is strongest together than apart.  She supplements the Coven's strength by studying the Magical Craft to Create magical fetishes and tools for her sisters to use, and mentoring the young witchlings that are not quite ready to fully participate in the Coven's business.
