Ok, I just got the 'Aliens' book and I'm working on the next adventure for my group. The idea is this. The crew discovers a crashed Borg cube, very much incapacitated, and begin to investigate the wreck. At the same time, an El-Aurian is raiding the crash, trying to find a way into the collective. He has issues. Anyway, he's using Breen rouges to do his dirty work, because their protective suits will easily protect them from the toxic fumes that the wreck had been burning off. Of course, the Borg aren't down for the count.
Now, reading up on the Breen, it turns out they're basically walking medical gel packs. Do you think it would be possible for the Borg to assimilate them, or more importantly, would the Borg even want them assimilated?
