This is Swartt Sixclaw the ferret warlord, the main villain of Outcast of Redwall by Brian Jaques! It was an amazing book! I was absolutely blown away. I also really liked how each character had their own accents and ways of speaking, like Swartt's "Oi ye slimy searats, catch that there smelly badg'r or off wit your 'eds!" It really made each character unique. :> I won't give any spoilers, though, but Swartt is a real heccin stinker.
