Great Escape

So you need a huge battery or something to get out of here? Well... I’ve seen something like that. Somewhere in these catacombs, there’s a cage with a huge demon. They call him Astral Butcher, huh.
They tried to make me get into that brute’s mind, or whatever demons have for it. What do you mean, what for? To subjugate him, of course! Imagine the power the Empire could have if it learned how to control Astral demons!
The thing is, they keep the Butcher in a stronger cage than mine. It is powered by a huge machine - I bet that’s the reactor.
If we break in there, you will have your way out!

Seems like you haven’t created any paradoxes yet. And the world is not eager to erase you from the tissue of existence. Thus, I assume that everything is going according to the plan.
So, what do we have here?
