When I enter Dragonsreach I emit a "burst" that levels up my destruction and kills someone and then makes all of the NPCs come after me. I've reloaded old saves and tried going there to no avail and I've reloaded to the same save to see if it was a glitch but I have the same luck. I'm now just avoiding Dragonsreach and using an old save, but does anyone know what it could be (and how I can stop it)?
Update: I went and assaulted a gaurd and paid off my bounty to see if that would fix it and it doesn't. Also it's totally a gigantic lightning bolt. But again, I'm not the source.
