Once I made contact with the stray colonist I explained where and when we are, and tried to describe the threat we're facing.
I'm guessing that was probably a lot to absorb, depending on information recall from the Genesis simulation. I beamed over some schematics of the local subsurface crawlways and conduits, hopefully with the access hatches clearly highlighted.
Then I shut it all down and waited.
I had a long wait.
Almost half a cycle passed before something tripped the silent alarm I'd set on the hatches in this sector. My heart was in my throat-what was I going to do if one of those monstrosities found its way down here to me, wave a soil probe at it?
Lucky for me, it was just my new friend, the colonist.
I took it as a good sign that my colonist friend was conscientious enough to seal the hatch again.
Plus, I wasn't alone anymore.
