Oh, yeah, I forgot about that... *Mortar takes a moment, then speaks again* Well, this is primarily a holding cell. The steam that is coming off of the spirits is actually some weird type of "Ether" and it's what powers this place. So, you're a walking talking power generator... *He doesn't want to mention the last part, because that is when, when the spirit weakens it's ether flow with age, they get put in a massive chamber, having every little droplet of it removed, and their soul being reborn as one of the imps or bottom level demons*
