Graylunk

Graylunk was a male weasel corsair of the ship Waveworm under Captain Conva. He was a member of the crew sent to murder the otters of Holt Lutra and to take the Tears of all Oceans. However, he and his friend Flairnose stole the pearls, which were meant to be taken back to Ublaz Mad Eyes, and fled into Mossflower Woods. On the way, the two weasels fought over the pearls and Graylunk killed Conva, but received an awful skullwound in the process. He ended up at Redwall Abbey, where he befriended the old squirrel Fermald. Fermald befriended the injured weasel and attempted to make his life happy and comfortable before his inevitable death.

When Graylunk wandered off to Mossflower to finally die from his grievous injuries, Fermald hid the pearls he had stolen throughout the abbey.
