What things would your world never countenance, no matter what the provocation, and what led to your created setting/characters coming up with this? Limits are not just about physical boundaries after all so what would your world set as its restrictions? Has it set these up to protect itself (and has it had cause to worry about this?).
What situations would make your world reconsider its restrictions? Does democracy exist on your world or, as in the case of the wonderful Havelock, Lord Vetinari of Discworld fame is the situation there "one man, one vote" and he is the one with the vote!
And how are politics organised on your world? How do they affect the characters you write about?
