Chief Engineer Elena
The buried structure isn't Corruption architecture, isn't Cygnus, isn't anything on any registry - old or new. Whatever's sleeping down there, the hive-mind wasn't leading it. It was reporting to it.
Jane Doe
So the plague that ate Perimeter Six was just... a middleman.
PILOT
Then we go introduce ourselves to management. Carefully.

Chief Engineer Elena
It's silent. Fully, finally silent. Whatever it was, it isn't listening anymore - not through the hive-mind, not through anything left standing down here.
Jane Doe
You don't sound relieved.
Chief Engineer Elena
I'm not. Something that patient doesn't sleep by accident. It was waiting for something. I'd very much like to know what it was waiting for before it wakes up on its own schedule instead of ours.
PILOT
Then we make sure we're ready either way. Let's get everyone home.

Jane Doe
Something is waiting at the heart of the ruin. Old, patient, and very much NOT the thing that has been giving the Corruption its orders.
Chief Engineer Elena
Find out exactly what the hive-mind was actually serving. I want a name for whatever we have been fighting a shadow of.
PILOT
And if it does not want to give us a name?
Jane Doe
Then we take the introduction the hard way. Same as everything else out here.

"Observer"
You have found the Choir's resting chamber. Congratulations. You are the first to ask the right question in longer than your species has existed.
Chief Engineer Elena
That is not an answer.
"Observer"
It is the beginning of one. Sit with that for now.
