Sacred Haven of Debauchery

where it is stated what contradicts and what does not.

I can elaborate if you're interested. These rules are indeed unwritten, but any player in an expedition can tell you in detail what is good and what is bad. For example:
GM: Your character is dead.
Player: No, he's not dead. I'm going to kill the enemy.
This is obviously bad. ;)
We come up with our own scenarios; we don't take them from others or from games.
