Entry 28 - Day 13

Okay, I don't know what I just found, but it was huge and old and fakking alien.

I got inside the structure through an undersea entrance and it was so beautiful.

There were vast rooms and corridors on different levels, all connected by ramps.  Some of the walls glowed, like they had a form of lighting built into them.  There weren't any doors, but some of the areas were blocked off by energy forcefields of some kind.  It's the most incredible thing I've ever seen.  I can't even begin to imagine the technology involved.

I've scanned everything I can find, since I was sure that Alterra would want all the data I could get, and then headed back to where I came in.  All of this won't be worth anything if I miss the Sunbeam and end up stranded here.
