Respect your elders, for if they notice you your head explodes!
Don't play with fire, it does aggravated damage.
Say "Thank You" when you eat something, because even if nobody else is around, the person you kill may come back as a wraith.
Any hierarchy, no matter how benevolent, will eventually become corrupt and take over the known world.
Birth defects, homelessness, rampant consumerism, the hole in the ozone layer, hate, malice, greed, alcoholism, the destruction of the Native Americans, bad television programming, violence in the media and strange chemicals in fast food can all be safely blamed on a supernatural entity.....usually Pentex
Almost anything, including artistic disembowelments, can be justified
1) in the name of Gaia,
2) if you're 300+ years old, or
3) if you've been doing it long enough.
Everything dies -- Garou, mages, changelings -- but they can come back in Wraith, and major villains can return in the next book.
Murder is okay if it's done with style (or, as above, for Gaia).
Stygian Iron is forever.
Tormenting librarians and accountants is a perfectly acceptable method of artistic expression. So is live rune-carving...if your Sabbot
The laws of reality are immutable, unless you buy the Players Guide.
It's always darkest before the Apocalypse.
Not only are the Garou sexy, they have RULES for being sexy--page 218.
Reality is a user-defined parameter.
Every alley in the city is the site of some sort of illegal sex trade.
When in doubt, blame it on the Nosferatu, or possibly on the Celestial Chorus.
The only right (Tradition, tribe, clan, kith, guild) is your (Tradition, tribe, clan, kith, guild) and all other should be (outmoded, eviscerated, diablerized, ignored, Oblivated).
Reality is like a parent: It has strict rules which cannot be broken, and it is all set to break them in order to PUNISH your ass...But only if your a Mage!
If you can't justify violent crime in the name of Gaia or by dint of obvious natural superiority, change legacies and go Unseelie.
Evil ALWAYS gets its own sourcebook.
The government isn't a puppet of Big Business, it is a pawn of the Wyrm. If the Technocracy are mages, and Vampires are Reality Deviants...Why does reality Punish the Technocracy?
If you don't like the rules, wait for the next book, they'll change
If no one notices you doing it, it didn't happen....Ask the Nosferatu, He saw you even if you did not do it...and he has pictures!
