The world, standing on the brink of disaster, can be saved only at the very last moment - this is one of the laws of the universe. Servants of the Order of St. Roland do not have the right to shoot at each other - this is the fourth rule of the shooter. None of the servants of the Order of St. Roland should return to the lost monastery - this is the zero rule of the shooter. All the troubles that can happen will definitely happen - this is Murphy's law. Any problem can be solved creatively - this is the rule of Gorlogorius Chroupodianis. But when the world is on the verge of destruction and the situation requires drastic measures, everyone decides for himself what rules and laws he should follow, this is the THIRD RULE OF ARROW.
