The A-Z Levels

The A-Z levels are a series of dimensions, each getting worse as you further into the alphabet. The A level was described as a paradise. The last level is the Z level which is overrun with zombies and is impossible to survive. They used to allow visitors to go the Z level using advances safety bubbles, but the zombies become too intelligent, and that world was completely locked out to people. These worlds were created because of the Mountain Nation's time machine malfunctioned. These worlds get worse than the main CLS world starting at the halfway point. Level 13 is pretty much as bad as the regular CLS main world.
