The Extinction Chronicles is a series of routine content drops adding new Explorer Notes, Tek-themed Creatures, and Skins related to the DLCExtinction. It ran from June 19th, 2018 until November 6th, 2018.
These are what the explorer notes are summarized as and how they are described in Extinction's lore.
Extinction Chronicles 1
Note #1: A mysterious voice (later known as the One Who Waits/Homo Deus Helena) greets the reader and says that her thoughts are not the only touching the player but others as well. It is up to the player if they want to read them or not.
Helena Walker is breaking the fourth wall as not only is the reader reading this note, but other players are reading this note as well.
Note #2: The One Who Waits explains that everything has a limit and considered to be finite. She remarks at how players get through the game through either kindness or cruelty.
Note #3: The One Who Waits tells the reader that humans, whether alone or together, are helping each other. She also gives a hint of conditions: time and space in her point of view is more flexible than people previously thought.
The One Who Waits is Helena Walker who has become a Homo deus and because of that, things such as time and space are more understandable in her new state.
Extinction Chronicles 2
Note #4: The One Who Waits explains that she can easily deduce cause and effect with her reasoning but trying to deduce time itself requires all of her concentration. She notes that because she is somehow feeling seconds, minutes, hours, days, months, years, decades, and centuries all at once, she doesn't know how long she has been waiting.
Helena notes that she can now understand what causes something and its effects, but trying to understand time puts a strain on her. As a Homo deus, she can perfectly see things in great detail upon millions of images.
Note #5: The One Who Waits explains that the universe people and creatures live in is simply math the universe is an equation where the things inside that universe are a value that helps to factor in its equation. Futures has probabilities where there are infinite outcomes and she calculates for the most likely outcomes.
As a Homo Deus, Helena has been endlessly calculating outcomes and she presses on outcomes that are most likely.
Note #6: The One Who Waits wants the player to refer to her as the given moniker because she has waited for a seemingly endless amount of time.
Her explorer note section for the Extinction Chronicles is labeled as ???.
Extinction Chronicles 3
Note #7: The One Who Waits explains to the reader that her existence is where she has nearly perfect information while players have a finite amount of knowledge. She wants the reader to trust her intentions as well as not forcing the reader to believe in her but having the reader believe in her by their own free will.
Note #8: The One Who Waits tells the survivor that the ARKs (referred to as the System) have AIs that she can speak with, but can't alter since they too have their own will. She has changed each ARK system by tiny amounts that ended up making the player amongst the thousands of code and pieces.
In Extinction lore, Helena has endlessly experimented, tested, and implemented protocols that allowed survivors to be revived upon death and soon, the player was her success of survivors endlessly dying and respawning though at a fixed amount based on the ARK's resources.
Note #9: The One Who Waits explains that the ARK's guardians feel like tests but they are tests that play by broken rules. She advises the player to leave the ARKs because they are beginning to malfunction. She refers to herself, Mei-Yin and the Tek tribe that escaped through the Gateway Project.
Extinction Chronicles 4
Note #10: The ARKs have existed for billions of years. It is like an organic being by understanding the struggle to reach its goals, but it struggles on a larger, and far longer scale. She explains that the ARK can make effortless and quick calculations but time has caused it to make more errors, making it a finite system.
In Extinction lore, all the ARKs have a Reseed Protocol that calls all of them back to ground, but another prerequisite, Element toxicity rating, has caused the ARKs to become increasingly dangerous with the fantasy and sci-fi creatures.
Note #11: The One Who Waits explains that everything the ARK does such as leveling entire cities, and adding creatures based on fantasy, is for the greater good in achieving its goal. However, a mysterious force is constantly moving its goal out of its reach, causing it to make more erratic actions, and more errors that makes the ARK poisonous to life.
In Extinction lore, Element has constantly grown to a point the ARKs aren't able to remove all of it and as a result, the ARKs are in prolonged orbit.
Note #12: The One Who Waits says that the player is the only one capable of fixing the ARKs. She explains more of her living conditions as she isn't a carbon-based life form who lives in a different reality where she can't directly affect the physical world. She tells the player she has a gift in the form of a powerful weapon if they head down and enter the map of Extinction.
Helena, as The One Who Waits in the Extinction lore, says that she is living in a different reality and that she uses the survivors as her active force as she can't directly affect the physical world. The gift she mentions is the Mek, a creation made by Santiago.
Extinction Chronicles 5
Note #13: The One Who Waits advises the players to take shelter in the city of Sanctuary, and the Proto-ARKs that surround it as anywhere beyond their area is filled with death and dangers. She tells the player that the obelisks in the new area are proto-types of the ARK's obelisks.
Sanctuary, in-game and in-lore, is a relatively safe location for both the players and the survivors that will soon make Camp Omega while the Wasteland is a highly dangerous and hazardous area.
Note #14: The One Who Waits explains that the entire universe is just cause and effect where something had a beginning as the Proto-ARKs are a firm foundation of every ARK that is up in orbit.
Note #15: The One Who Waits notices that everything that happened on the mysterious planet (Earth) will either end where it began or sprout a new beginning, but she says that the outcome is still up to the player. She gives a fact that survival of a species requires the expense of another and remarks that where Homo Sapiens pushed the Neanderthals to extinction, a mysterious force is using powerful forces to push humanity to the same fate.
In The One Who Waits lore in Extinction, Element is the force that is pushing humanity to the same fate and is the enemy that the survivors will face.
