Multiverse

The **Multiverse**, also known as the **Omniverse**, was a concept that was present throughout the Aether Story of *Call of Duty: Zombies*. It is a collection of differing universes, dimensions, and timelines, each of them different in their own way.

## Overview

―Kronorium Excerpt 349561223

Initially in the Aether Story, there were only a few differing universes, most of them known as **Dimensions**. The specific number of universes is unknown, but it is known that there are at least 2210 of them. Initially, the multiverse was seeded with life by a Keeper known as the "First One" with the Summoning Key. However, thanks to the effect of Element 115 across the multiverse, other chaotic dimensions began to appear across the multiverse.

### Agartha

―Doctor Monty

*Main article: Agartha*

**Agartha** is the first dimension to come into existence, and exists outside of the rest of the multiverse. It was created and inhabited by the ancient race known as the Keepers by utilizing the power of the Summoning Key and the Aether. It was once at peace, until a group of Keepers led by a being who would come to be known as the Shadowman discovered a realm known as the Dark Aether, leading to a war between these Keepers and the rest of their kind. After this, the Keepers became the protectors of all creation, with a Keeper known as Doctor Monty taking control over the realm.

### Dark Aether

*Main article: Dark Aether*
The **Dark Aether** is a dimension of darkness, evil, and corruption that became the home of the Apothicons after their defeat during the War of Agartha.

### Crossover Timeline

The **Crossover Timeline** refers to the Dimension that most of *The Walking Dead X Call of Duty Zombies* series takes place in. It was once a normal universe similar to that of both *The Walking Dead* comics and the video game series by Telltale Games. However, thanks to Element 115, this universe became interwoven into the Aether.

### Original Timeline (*Call of Duty Zombies*)

The **Original Timeline** refers to the Dimension that most of the Aether Story takes place in. It was (retroactively) introduced in *Call of Duty: World at War*, and has appeared in every title involving the Aether Story. In this universe, The Great War occurs but is quickly lost to time and forgotten. Group 935 is founded in the 1930's by Doctor Ludvig Maxis, with one of their scientists, Edward Richtofen, forming a crew known as "Ultimis" with his former test subjects in a bid to gain control over the Aether itself.

### Dimension 63

**Dimension 63** is a Dimension introduced in *Call of Duty: Black Ops II*, appearing in every game involving the Aether Story since. In this universe, The Great War occurs and is remembered thanks to the journal of Pablo Marinus, which would be discovered by Group 935 (which itself would be founded some time before 1912). This Dimension differs mainly from the fact that technology advances further and quicker than it does in the Original Timeline, thanks to the full utilization of Element 115-empowered technology during World War I.

### Original Timeline (*The Walking Dead*)

The **Original Timeline** refers to a universe that was written by Robert Kirkman. It takes place within Telltale Games' *The Walking Dead video game's* universe, which takes place within Robert Kirkman's comic book universe.

### "Walden" Timeline

The "Walden Timeline" refers to another alternate version of Robert Kirkman's comic book universe written by Tillie Walden.
