The code void

The code void is an ancient and unknowable force of chaos that surrounds The world tree and all of known reality which formed trillions of years ago and Blocked the Almighty hand from interacting with the Omniverse. Anyone and everyone that makes contact with the code void is either destroyed by unraveled into code which is then absorbed into the void or if they live they are driven insane with visions of What Lies Beyond. No man nor god can pierce the code void with any known power or weapon.

Even if they were able to get past the code void there would be more behind it. It is unknown how many walls there are as nobody has ever even heard of someone getting past the first
