Greyf was an Atmoran warrior. She was one of the Five Hundred Companions, and was married to Breff the Elder. Greyf and her husband were both a part of the Krilot Lok crew.


After safely reaching Mereth and reclaiming Saarthal, the Circle of Captains was assembled. It was decided that every captain and his crew should go their own ways. Unlike most of the bands, Krilot Lok went back to the sea. It is said that they visited Yokuda and encountered Redguards long before they settled on Tamriel.

The crew of Krilot Lok visited many lands along the shores of Tamriel, including the great deserts of Elsweyr and the southern marsh later known by the name of Black Marsh.
