Arkn: Eternal is yet another addition to the web-based Arkn Mythos franchise. It was created by DeathlyLogic, and originally launched on December 25, 2018, with the finale of Solar's Crimson. A Spin-Off of The Arknverse, Eternal was intended to allow incoming creators to produce content in a setting similar to that of The Arknverse, without disturbing the canon ending of that franchise. When no content emerged for Eternal after nearly two years, however, DeathlyLogic decided to reboot Eternal. The end result is an all-new version of Arkn: Eternal, with a new backstory, new settings, new characters, and a new, upcoming series: The Seven Circles.
Azrael Michaelis Winter, having spent eons learning to master his time-based powers, decides to Time Travel to the golden age of the Arkn and prevent the second Arkn-Dekn conflict. However, he overshoots his stopping point, instead arriving before the dawn of time, just as the Hethe first appear. Azrael's presence alters crucial points in the timeline, causing a ripple in the fabric of reality that splits off the new version of events into a new, separate version of the universe he knows: Universe E.
Arkn: Eternal provides examples of:
- Alternate Universe: Universe E is an AU of Universe A in which the Arkn-Dekn conflict was prevented. It resembles an Alternate Timeline in most aspects, right down to running parallel to (and being able to cross over with) Universe X. However, since time is an aspect of Existence normally only experienced by mortal beings,note Azrael's manipulation of events — which removed numerous fixed points — caused ripples in the fabric of reality, so drastic that it split the "new" set of events off into their own universe (rather than a mere parallel timeline).
- Forever War: Subverted; in Universe E, the war between the Arkn and the Dekn is prevented before it even begins.
- Kill the God: The first story of The Seven Circles shows a mysterious figure killing the Hethe in their realm of Xua.
- Set Right What Once Went Wrong: Due to how events unfolded in original history (beginning with the first King of the Arkn, Gilgamesh, being defeated by The Carver) The Carver had the upper hand against the Arkn from the very start; Azrael attempts to travel back to the golden age of Gilgamesh's reign and ensure that The Carver was defeated. However, he instead arrives at precisely the moment the Hethe first appear. He uses this to his advantage, educating the Hethe on the disastrous state of Arknverse A and the various roles they played in it; this convinces most of the Hethe to pursue a more peaceful path in creation. After the first Dekn, Hash'bor'kanibal, is created, De'ebo becomes bored at the placid state of Existence, and attempts to create the Arkn in secret and encourage them to war against the Dekn. Gar'sha discovers his treachery, and De'ebo is brought to justice, with the Hethe (and Azrael) using their combined power to seal De'ebo away.
- Sealed Evil in a Can: As punishment for attempting to create the Arkn and pit them against the Dekn, De'ebo is sealed away in a small cube dimension. Whether he ever escapes from said cube is unknown. (However, the first planned story for The Seven Circles had a mysterious figure killing the Hethe, hinting at the possibility.)
- Temporal Paradox: Averted, due to the "ripple" in time causing the new version of events to split off into their own universe.
