the skeleton in the quarry was Graylunk. He had become gravely injured in a fight with the weasel Flairnose, whom he killed, over the pearls before seeking safety at Redwall. There he befriended an old squirrel called Sister Fermald before he went off to die in the woods. Fermald, a clever, though senile old beast, had expertly hidden the pearls throughout the abbey before passing away several seasons ago. Tansy, Rollo, and Martin II, along with the hedgehog maid's friends Craklyn the squirrel and Piknim the mouse, begin a search for the six exquisite pearls. The Dibbun Arven and his two partners in crime, the moles Diggum and Gurrbowl, occasionally help in the search. When Abbot Durral takes young Viola Bankvole for a stroll in Mossflower Woods, they are captured by Lask and his troops. Lask binds the Abbot and the bankvole and attempts to ransom them for the pearls at Redwall. However, the pearls have not yet been found, and Lask and his lizards take the two Redwallers back to their ship to be captives at Sampetra. Martin, Clecky, Gerul, and the Skipper of Otters pursue the lizards through Mossflower, slaying several but failing to rescue the captives. Gerul and Skipper become wounded and are sent back to the Abbey, but the others chase the lizards to the western shore. There, they meet up with the GUOSSSIM and Grath Longfletch, who had caught sight of Romsca's ship, the Waveworm, and attempted to pick off some of the vermin. Durral manages to help Viola get to safety on the shore, but the ship departs before he can escape. Viola is sent back to Redwall with two shrews to guide her, and Grath, Clecky, Martin, and the Log-a-Log's two sons use discarded vermin boats to form the Freebeast, a double-outrigger vessel in which they pursue Lask to Sampetra. Viola, who has sneaked aboard, also ends up coming along. On Sampetra, Barranca has been slain by Rasconza, a clever fox corsair who takes over the rebellion against Ublaz. Initial attempts at negotiation fail, due to the double-dealing of the pair, and when Ublaz tries to have Rasconza assassinated, Sampetra is plunged into all-out war. Ublaz's trident-rats, led by his general Sagitar, desert him and switch to Rasconza's side, but they are unable to take Ublaz's fortress, which is still held by his monitor lizards. Under siege, Ublaz decides to hold out until
