Invitation for what? lol
The invitation is to go along with us when we take off for Mars.
There are rules, I suppose, but they are not tricky. Mostly it is for the protection of all.
Anyone who threatens the ship through sabotage, will be considered in violation of the rules.
Unwarranted murder, without justification.
Deliberately destructive mayhem. (Darksheare, keep the powder loads within reason, please!)
I'm sure you see the direction this takes. Ours is not a dictatorship, it's just a regular ship, and the safety of the crew and the ship is paramount.
