This city is afraid of me. I have seen its true face. The streets are extended gutters and the gutters are full of blood and when the drains finally scab over, all the vermin will drown.

Sage is driven by a deep personal quest for philosophical meaning, which has taken him through both Objectivism, Zen; in some versions he is portrayed as a paranoid conspiracy theorist.
