Thanks! They can go full Borg, Communion isn't big on control. I see it more as an analogy to an online community; what looks like unified movement is more like Reddit when they got invested in the Boston bomber - some of them are quick to jump to action, and once a few go, there's a strong bandwagon effect.

Most of the time, they can't hear them at all - the macguffin they tripped over originally was a kind of psychic repeater that ties Communion together. Without something like that, they're out of contact, and can only use the memories they already received to advance (or learn the old fashioned way). They could set something like that up, but I don't think they will; they've known how to rebuild it since the first data dump. But the player who's been enhancing himself seems pretty hell-bent on becoming a steampunk cyber-dragon!
