Preview of the Halloween event on CoH

So, on the City of Heroes' Test server yesterday, they tested for an hour and a half the upcoming Halloween event. There's a new invasion event that needed testing.

( Cut for not spoilering the event? For those who don't mind, click away! )

The prevailing theory on the Test forum is that they're testing the Halloween event so early, because Test server might be testing an issue when they would normally test the Halloween event coding. We shall see.
