Fleng was a scorecat in Riggu Felis' feral cat army on Green Isle. In the retaliation attack against the outlaw otter clans, Riggu Felis sent Fleng and twenty guards to pursue their enemies inland, promising to follow up behind. Riggu's true plot was to use Fleng as a diversion, while the rest of the army moved to the coast to seek out and destroy the otter's homes and families.
