Corriam Wildlough was a male otter resident of Green Isle. He was the brother of the original High Rhulain Wildlough, husband of Runa Wildlough, son-in-law of Alem Mossguard, and the ancestor of Banjon Wildlough and Tiria Wildlough.
Corriam was stranded with only his lance and his sister's coronet after their ship was destroyed while they were tracking wildcats. He was found on a beach, close to death, and nursed back to health by Runa. When he had recovered, Runa became close to him, but her father Alem Mossguard disapproved.
Runa and Corriam eventually journeyed to Redwall Abbey and married, where he repaired his lance. After his death, Runa entrusted the coronet and Corriam's lance to Sister Geminya, who hid these items in her room near the top of the Abbey, cleverly using the lance as a curtain rail with the coronet inside it.
