Hmm. Some thought, and here are a few suggestions:
Impetus
Single word. Goes with Infernal a little bit, and describes Jack, kind of.
Refraction
Another single word. And actually relates a bit to "visions." After all, refraction is something that happens to light. In fact, the first word from the Wikipedia definition is just about the coolest sentence ever: "Refraction in geometric optics is the change in direction of a wave due to a change in velocity."
Descent
Pretty much just a cool word.
Cogs
Goes along with "precognition" as well as indicating how Jack sometimes feels like a pawn in a massive game between two huge powers. A "cog" in the machine, so to speak.
Throughout our history there are those ghosts
Compelled to illustrate our dreams and hopes
Victors hang in pictures, losers from ropes.
Regardless they all swing in the same boat.
