Ruis is a high druid who spends most of her time at Tara. She is an older cousin of Flidais. Occasionally she visits Inver Colpa or accompanies Clan Niafer on a raid, quest, or other escapade. Not only is she knowledgable in the laws and the lore of Eire, but she has traveled far abroad to study and seek initiations into the mystic realms of other lands, delving into the Elysian mysteries, the cult of Demeter, and many more secrets. She is a brehon, a seer, and usually leads the rituals for the main festivals.
