Black Diggers

What do you mean, who? My girls saw a dozen of other Alliance fighters, going through Architects' remains to the east from Fractal. And then you came and asked me to deliver the wrecks to the city. I thought you were from the same troop!
So you don't know who they are? This is very strange. Nobody is supposed to be on the Bee Ravine right now. We need to check on those black diggers...

Who are those soldiers who dig through the Architects' wrecks on the east? This seems odd...

So those are the bastards who had deserted to the enemy?! Oh I will grind them to dust! I will send a whole squadron to eliminate them!
