Just a suggestion for an additional event. The turrets (the vanilla ones anyhow) aren't top notch and are easily faulty. Because of this, an event could be a single turret goes rogue as it can't identify friend from foe. Whether or not it has to be destroyed or eventually wears off is up to whoever decides to do this, be it in mod form or by Tynan.
Turn off power = Threat negated
That's an easy way to manage it, but if the event came in a really bad time like a raiding party, it'd make things that much more difficult.
I like it!
