A book appeared in front of Atticus the moment he selected it in his mind.
Written boldly on its cover was: The Laws of the Middle Plane.
Atticus didn't waste time and quickly dove into it. The laws were… a whole lot, and while he had initially wondered why a whole book was needed for it, he understood the moment he read through it. It didn't even take up to a nanosecond.
Atticus silently absorbed everything he'd just read.
'It's simple and straightforward.'
While Atticus thought this, he didn't really believe it. Different laws filled every inch of the book, and most of them had been made to reinforce what Atticus considered the main rules.
Rent must be paid every two years for the rules to apply to the gods and their world(s). Consent must be given by both parties in order to engage in battle.
The gods of each world had to give permission before any other god, or inhabitants of other worlds, could enter their world.
