Nova wouldn't have to worry about Saber teleporting. Saber and Absolis would probably side with Nova.
I will keep a special cache of low-tech weapons and train my troops in their use. That way -- even if the heroes manage to neutralize my power generator and/or render the standard-issue energy weapons useless -- my troops will not be overrun by a handful of savages armed with spears and rocks.
@Absolis
At that level of power, it's no longer an anti-machine weaponry. The sheer amount of energy would cook any living being that came into contact with it, and boil the atmosphere. Sure, you'd fry machinery. But that would be the secondary effect. Any machine you would affect would be destroyed by the heat far more quickly than the electromagnetic field.

Well, this argument at the moment is invalid anyway since Ba'al doesn't actually know where the labs are and can't exactly send a fleet thee in the first place. But I would point out that the Goa'uld also have gravity manipulation technology (albeit not on such a large scale) and cold fusion weaponry too. And that's before getting into the Ancient technology recovered from Atlantis and other places.

Force fields are a wonderful thing :V
