Captain's log - Stardate 2261.347

We beamed down to the surface to search for Bones and instead found this . . . thing. I asked Spock what the hell it was and the thing lit up and spoke back. It even began displaying old Earth history - pre-Imperial days. While we were distracted by the images, Bones darted out from wherever he'd been hiding and jumped into the images before we could react.

The images immediately disappeared and when Spock questioned why they had stopped, we were informed that the past we had been observing was no more. Dammit, now what?
