/cgl/ - Cosplay & EGL

I know a lot of you go to Drachenfest, so I'm sure someone here can explain this to me:

The rulebook states that when you die at DF, you get sucked into a dungeon representing limbo. If you can talk/run/whatever your way out of there, you can go back to play, else the character is dead. Makes sense. However, Drachenfest is a PvP event with ~4500 participants. I'd assume that during large battles, hundreds of people will go down. How does that work? Do loads of people run through there all at once? Do people have to queue up and go through there one by one? Or is there some kind of 'no permadeath during large battles' rule?
