It's been awhile since I checked out FAB, but doesn't that stuff take a good long time to degrade magic? And can't you just use a Sterilize spell to kill it? I don't see how it would be a threat to mages of any sort if so. Awakened beings, adepts and critters yeah but if they can sling mojo it shouldn't be anything more than an inconvenience.
But onto my own "what if".
I'd like to see a "What If" NORAD really was suborned into "the Strategic Bug Command" like is alluded to in the Denver box set. A Un-nukeable and damn near un-asailable fortress for the bugs to spawn until their little hearts are content right in the middle (relatively) of the country. You could even tie this into loosing track of all those operatives from those Ares R and D Bug facilities they lost track of...... Or to the bug hybrids in Conspiracy Theories.
Frankly, I just love the bugs as villains in runs.
