The GG's origins are crazy to think about, possibility wise. But they seemed to have sucked up Scorpions for certain, Ice Hellions for certain, and who knows about other Clans, but yeah, I think GG's are a viable place for Clanners to go when they die. ;D But that's not something I would think the WoB would do. They have WoB equipment, they may have gotten to rob the WoB cache at Waystation 531, I think. But it could be a WoB enterprise, it probably has as good a chance of that being likely as anything else in the end. If it's not something new, which I hope it to be.
Maybe they have some Society in their ranks too.
