Ganno was a male otter of the outlaw otterclans on Green Isle. Early on in the battle with Riggu Felis and his Feral-Cat army of Green Isle, Ganno, along with Lugg, was sent out to scout the right bank of the Fortress lake. He was to look for any cat activity on the pier, see if the slaves were being heavily guarded, and try to spot Leatho Shellhound, who had been captured by the cats. When the two scouts returned to Banya, Lugg spoke for them both. There had been no activity outside the fortress, the slave compound was well-guarded, and they had not seen Leatho.
