In a way, I feel pity for him -- an emotion that I know will prevent my advancement beyond the Third Rank -- but it is pity I feel nonetheless. He has spent most of his time below in the technology archive, staring at the ancient cross above his head. He burns with a hatred that I can feel, for himself and for someone else. Periodically he will receive holographic communications from Simons, after which his hatred burns all the brighter. I think it has burned away everything human in him, and only the metal holds him together anymore...
