In LARP, much like any other game, there are rules. Some rules can be bent. Others can be broken. However, in the Mind's Eye Theatre system, which most White Wolf LARP games are governed by, there are a set of rules that should never be broken. Mind's Eye Theatre refers to these as The Rules Thou Shalt Never Break.
It should be pointed out that violations of these rules, should it be proven that such incidents deter from the game's purpose — to have fun in a safe and meaningful way without disrupting real-life happenings around you — will result in immediate and harsh punishment, up to and including an immediate and permanent ban from the game. You Have Been Warned.
