The Arkn Mythos is a Mythos centering around an eternal War between Arkn and Dekn, Humanity, and much more! A large majority of its stories are told through webseries and written works, While creating massive portions of added canon is done privately with the active admins of the universe wished for creation, the Arkn Mythos is seen as open source, and creating original stories in it is encouraged. Admins/Owners of the wiki and general "official" communities are Deathlylogic and Kekstein
Currently, the Mythos is split into two canon Universes: UniverseA, and Universe X. There is also Universe F: a non-canon "universe" for free writing; here, absolutely anything goes, without the need to abide by canon. Works will remain constrained to their respective universes, unless the creator is otherwise given permission.
The Arkn Mythos is seen as a standalone storybook. Creations done combining Arkn content with any outside content can be done within the Arkn Mythos Extended UniverseF (otherwise known as The Alterverse). Any work created under the Alterverse is non-canon, and not connected to the other two universes.
The Arkn Mythos is divided into multiple sections, depending on where one wishes to create.
The content of Universe A (or The Arknverse) falls under two major categories. The first category, the Arknthology, is the myth arc of Universe A: the bigger, overarching story told by a collection of series that play directly off the Universe's lore. The second category, Chronologies are stories involving primarily standalone series, or works creating their own lore. The difference between the two is that the Arknthology plays on and advances the lore of the Mythos itself, while the Chronologies advance self-contained lore within the stories. Note: As of 2018, the ending of the Arknthology has been finalized. However, it is still possible to create within Universe A, provided you don't contradict the canon "ending" of the Universe.
The Universe X (or Arkn: Legacy) sequel/expansion has added two new categories: the X-Omnibus, and Legacy Chronologies. These work the same way as the Universe A categories, with X-Omnibus acting as a myth arc (of sorts) and Chronologies being stand-alone. Everything within Legacy, unless specified by the work's creators, is seen as self contained.
Non-canon, stand-alone works are contained within Universe F, the Alterverse or Extended Universe. There is no set canon and no ongoing storylines in this "Universe". Stand-alone works based on both the Arknverse and Legacy can be added under Universe F.
Disclaimer: Work within this Universe is non-canon, and cannot carry over to any other universe unless approved by one of the Admins. This is in place to let people do what they want with the content they are using.
