The master password allows you to go in as the player who quit, which allows you to set it to AI. If it's real early in the game, it's even better to get someone who isn't in the game to do so, because otherwise you wind up knowing where the other nation started/is.

Edit: For that matter, since Agrajag foolishly posted his passwords for any and all to see, you could've used that to go in and set to AI even if you didn't have a master password.

In case Agrajag is reading : Posting the passwords for the public was incredibly foolish, because then _any_ one could go in, change orders, send gems to themselves, or simply spy on what orders had been given.

In effect, it poisoned the nation, because any replacement player can't change the password, and thus has no control over whether or not someone else wants to cheat or simply amuse themselves by screwing with it.
