During the "Writing is Magic" panel at Bronycon (July 1st) one of the light fixtures in the middle of the 'Mane Hall' (amazing pun) probably shorted, causing the plastic cover to be set on fire, and melt, showering the concrete floor below with magmaesque melted flaming plastic. Everypony was evacuated out of the hall, and nobody was hurt. Within an hour, everything was back to normal!

I used the ANTI SHAKE thing that youtube offered me, and it makes the video look really awkward looking, but it helps you see a bit better. I dont know if it was my hands shaking, or whether I was being shoved by staff  to GTFO.

Jeeze, I dont care about my safety! All I want is to get famous! Durrr.
While standing outside with everypony else that was evacuated, everyone seemed to be blaming it either on discord, derpy, or themselves. I have my bets on discord, which means the ponies are real... somewhere! Begging for us to build a spaceship and come find them! ;)
