I became one of the monsters that guarded Walter's throne. The green stone became mine to keep, to be given only to the one who defeated me, and in so doing released me. Rinaldo never reached me, which was perhaps for the best. Walter took great care to tell me how the human had been brought low by the Succubus' illusions.
Five swords were given into my command; each so huge I could only wield it by vampiric strength. In a very short time I had learned to the throw them about by the simple power of my mind. Walter seemed truly concerned that I never be beaten and after one close fight he added three mystic orbs, which shielded me until all were removed. To make future battles harder, the orbs regenerated.
To an extent, I was grateful for the shield. I figured that if a hunter could not overcome MY shield, then they could not hope to defeat Walter. If that were true, Walter would reign for a very long time. Only a hand-full of warriors succeeded in hurting me, and in every case they were too far spent to win. Not many hunters reached me, however. My part of the castle was the most heavily guarded, with the most fiendish traps, second only to the Pagoda of the Misty Moon, where Walter himself waited.
Time passed very slowly, with only the relentless sound of running water coming faintly to my room. I came to hate that room very quickly, and of course, I could never leave it. After a time, with nobody but hunters coming for me, I began to go quite mad.
