They also seemed to enter a similar state to good 'ol Ranjit. Not a 1-1, obviously, but that's cool as hell. There wasn't nearly enough shown to demonstrate how they'd function AS a melee DPS besides the obvious, though.

As for lore, 99% of voidsent stuff either has them being invasive, or specifically bound. This seems far more mutual, so I'm super curious what comes of it.
