Infinite Mana In The Apocalypse

I looked at the rotating hexagonal prism in the blank room as I could feel my heart that wasn't physically in this space start pounding. I heard the bland voice that called out the greeting in my head as I looked away from the smaller three rooms and replied, "What, err, who are you and where am I?"

I placed my hand on my chest to feel my actual body as I recalled the sensation of not having any limbs or body in the blank space a moment ago. I had to wrap up and hurry to the United Federation to take down another one of these beasts, and after that...I should be able to get more answers
