I don't think it's the kind of energy that powers machines. It's something different. More like... life energy, I guess. The miasma- that's what makes you sick if you don't get enough touch- sucks all up or destroys it or something and the people who live here can't make more themselves. That's why they need us. If we all left, they wouldn't be able to make more life-energy, and they'd all die.

And yeah not everybody does. But you'd probly like being sick even less. [Pause] Have you made any friends here? It's usually easier with them than just asking a random person.
