High Queen Rhulain Wildlough was the first known otter High Rhulain of Green Isle. She was the sister of Corriam Wildlough, sister-in-law to Runa Wildlough, and the ancestor of Banjon Wildlough and Tiria Wildlough.
When her ship crashed against rocks in the sea after being pursued by wildcats, near Salamandastron, the cats swarmed aboard and killed her, despite the best efforts of her guards, her brother Corriam Wildlough, and herself to drive them off. In her absence, the wildcats conquered Green Isle and enslaved its inhabitants.
She appeared alongside Martin the Warrior in Tiria's dreams as a cloaked figure, telling riddles to the young otter.
