Rumor: [ Lotus storm caused the event to start by doing some silithus raid quest ]
Anyways, I wouldnt worry about this event staying, it would be insane for them to do so, especially with atleast 50% of the pop play here because they wanted a fresh start..
I wouldnt recommend doing anything with the AQ npcs, your rep and items you gained from them might be removed and items and money you spent not returned, since its probably considered to be an exploit
