The Kronorium is an item referred to in Call of Duty: Black Ops III in several Zombies maps. This ancient book contains information regarding the universes, dimensions, the Summoning Key and the history of several creatures, artifacts and creations.
In the Call of Duty: Zombies comic, Victis (the TranZit crew) searches for it with the help of Primis Edward Richtofen, who has asked them to conduct said research. In Revelations, it is found in The House in Samantha's room, where it is used to regain the Summoning Key and ultimately kill the Shadowman. It has been confirmed that the Kronorium holds the entire zombies timeline ranging from Dimension 63 all the way to Fractures.
There are seven ciphers that reveal excerpts throughout Gorod Krovi; currently only five of the seven have been decoded:
- "In the beginning, there were only the Keepers. But then corruption of the dark Aether leached its way into the realm and twisted the minds of some of the Keepers. These Keepers turn into shadows of their former selves and eventually became Apothicons"
- — Excerpt Unknown
- "To allow quick travel between dimensions, the Keepers created a transference device which is powered by the Aether. The Keepers have placed structures throughout the realms."
- — Excerpt B
- "The life force from the Dead World allows the bearer to flow with all creation."
- — Excerpt 27101978
- "The Summoning Key is one of the oldest artifacts in all creation. It was used by the first one to mix all the dimensions with life, giving each one its unique balance. Under certain circumstances, it has the ability to form bridges between dimensions allowing the transfer of life forces back and forth. It resides in the 63rd dimensions of creation."
- — Excerpt 349561223
- "Once the great war ended with the defeat of the Apothicons, the Keepers ascended to become the wards of all universes. The surviving Apothicons were cast out, banished to the dark Aether beneath creation. After eons of exile in the dark Aether, the Apothicons evolved into twisted creatures that now bear little resemblance to their Keeper brethren. The Apothicons' ceaseless desire is to reenter creation to consume and corrupt all universes. It is the Keepers that guard against these perpetual attempts of reenter creation, and guard against any beings that may have fallen under the influence of the Apothicons."
