Power Sink (raiders, sieges, and assassins)

[blank_asteroid]

A high-threat, huge-event level item that raiders/sieges/assassins sometimes place on accessible power lines. Any connections to that source lose power until the device is removed (attacking). Destroying the device grants moderate metal, etc.

I think spy events "saboteurs" should do this
