Mei's been getting me caught up while we repair her MEK. Apparently her friend from the other station, Helena, became delirious after using some kind of artifact to fend off those big monsters. Long story short, that stunt put her in a coma, and she ended up dissolving into a beam of light.
In other words, they were knee deep in some seriously trippy shit. Of course, I was recently resurrected and hear a voice in my head, so I can't exactly throw stones.
It's too bad about Helena. We got along well, even if I only knew her for a short time, and she risked her life to help us back in those caves. Whatever happened to her, I hope she's at peace.
