Session Zero
 
These are the rules which we play by. Break them, and you'll be ceremonially fed to Sonja the Red Dragon, and no, you won't be getting a Saving Throw!
What Sonja says, goes.
You're at Sonjas' Table. Sonja is the DM. What the DM says goes, is what goes. That means Sonja says what goes. Playing at Sonjas' Table is a privilege, not a right. Don't get your privilege revoked!
Anime catgirls
There are no anime catgirls. Yes it would be cool, but there aren't any, sorry!
Religion & Politics
Nope, nope, no real life religion/politics. We're not going there. I don't care who or what you believe in or how you vote.
Consequences
It's a fairly "open world" game, but bear in mind that Actions have Consequences. Eg., if you attack an NPC shop keeper and rob them, you may do so... but the Consequences will be that the City Guard will be after you and a price will be on your head!
PvP
Player vs Player is allowed, but within reason. Eg., if you have reason to believe someone is going to attack you, you can attack them first. However, there may well be Consequences for taking such action. Think before you Act!
"It's what my character would do."
This phrase does not excuse your actions. Expect a steely glare (at best) if you say this phrase.
Fade to Black
Certain things, while possible and allowed, just won't be a part of the game. Eg., you convince a bar maid to show you a good time in the cellar. This is possible and allowed, but will result in a Fade to Black; the actions take place but just are not part of the game and won't be roleplayed.
Sexual Assault
Both Astrid the Cat Goddess and Sonja the Red Dragon absolutely condemn sexual assault. Don't do it. Don't even try to do it. Don't hint about it. Really... don't. No exceptions.
