Head back to Oakfield and set the Hobbe Squatters quest. Assuming you didn't decimate the Temple of Light, you'll meet a rather odd character whose cave has been infested with Hobbes. Called Echo Mine, after accepting you need to fight your way through Hobbes outside and then down into the belly of the darkness. Battle the crowds of Hobbes inside and defeat their leader using ranged attacks and targeted Inferno. You may also be able to knock him off the bridge with powered up melee attacks. You get a Hobbe Leg trophy and 3500 renown for your troubles, but unfortunately for the man who sent you in it has emerged that he was trying to kill you, the now infamous hero of Albion. Give him what he deserves (no morality points gained or lost here) and get the hell out of there.
