"Well..." Maggie said, looking uncertain. "At the moment, Equestria and Project Harmonics are still top secret from the general public. We didn't want to get folks' hopes up until we were certain that we could move here.

If you really wanted to, though, I could authorize you to walk around the Harmonics labs, at least the secure sections. Would you like that?"
