Right, but let's say (perhaps due to Harlequin's recent actions involving magic EXTRAORDINARILY similar to the Great Ghost Dance) a few of them manage to slip through before the bridge gets closed (perhaps due to a combined IE/Dragon effort, as both Ghostwalker and Harley are probably aware of this one). Further, let's assume for the moment that the Azzies are not their only servants - for example, the Black Lodge could be theirs. So, they get through, and we've got some sort of secret conflict (the Enemy doesn't want everyone to know about them yet, and if those in the know haven't explained things yet they probably won't until everything truly hits the fan). One one side, you've got the dragons, the IE's (probably including both Tirs), SK, and NeoNET. Perhaps the bugs. On the other, you've got the Azzies, the Black Lodge (who can probably subvert the power of a few nations, at the very least, for their own ends). If the Invae go to the first side, Ares probably reflexively positions against them without any understanding of events. Horizon positions against Aztechnology, again without knowing what's going on. The Japanacorps see odd behaviour out of some of the other megas and move to take advantage. That leaves Evo and Wuxing as unknowns, but there's probably going to be enough going on with Evo as it is. It could be a very interesting metaplot direction.
Have the bugs been established in SR material to be against the Enemy? After all, anything that's established in Earthdawn and not SR could change.
