Quite late but I think this info might help you. Been checking the note Green gave you. Here's what I got:
Darkness will rise,
The light shall burn,
Evil is coming,
this world will turn.
Be vigilant, my child,
and trust in us.
Fire with fire
Pickaxe to stone
Fear the liar
while the truth is your own.
We are using the forces of darkness against the greatest darkness of all.
He is coming. He is rising
It talks about fighting darkness with darkness.
Can't make sense of it yet. Any ideas?
Michael Macready: Holy cow! How did you do it? I wonder what it means. Who is coming? Could it be the being I saw in the Blank Space? What should I do with this information? Should I ask Mr. Green? Maybe he might give me another weird riddle.
My current guess is that fighting fire with fire could be in reference to The Company's collection of Entities fighting against something. What do you think?
