|---|---|
| A splintered fragment of the same primordial power as the Ancients themselves, Zet endeavors to end the disharmony among the warring factions through whatever means necessary. Solitary foes are thrown into a volatile state of Flux, ripping away their health over time. Distorting space to generate a Protective Field sheltering around allies, evading and attacking with greater efficiency. Zet summons Spark Fragments of its former self that circles in place, and seek out nearby foes. Is there one Arc Warden, or two? Armed with the original's items and abilities, the Self's Tempest Double duplicates each spell and every attack, bringing twice the chaos to any fight. | |

Bio
[edit]It is not to aid the Ancients that this war is joined, but to destroy them both. This disunity must end.▶️Zet, the Arc Warden
Aliases:
AW, Zet
Lore:
Before the beginning of all, there existed a presence: a primordial mind, infinite, awesome, and set to inscrutable purpose. As the universe thundered into being, this mind was fragmented and scattered. Two among its greater fragments—who would come to be named Radiant and Dire--found themselves locked in vicious opposition, and began twisting all of creation to serve their conflict.
As war and cataclysm threatened the nascent cosmos, the will of a third fragment made itself known. Naming itself Zet, this intellect sought to resolve the disharmony and return all to perfect unity. Appalled by its kin's conflicting nature, Zet gathered the sum of its power. In a sudden flash, it overwhelmed its siblings, and fused the warring aspects into a stellar sphere before hurling them into the darkness to orbit a nondescript world. Harmony was restored, though only the barest fraction of Zet's strength remained. Setting its gaze on the prison, Zet chose to use its weakened power to serve as watchful warden until time's end. For uncounted aeons, this vigil stood.
Life flourished upon the world below, oblivious to the dangers imprisoned within the softly glowing moon, or of Zet's struggles to contain them. As the captives' eternal clash reverberated within, the surface of the prison shuddered, over time beginning to crack. Ultimately, Zet's depleted power proved insufficient to contain the breach, and at last the moon was shattered. The prison's ancient inhabitants had escaped to sow their conflict anew.
Flung to the farthest reaches by the prison's explosion, Zet was transformed by the dissonant energies of its former captives. No longer of single form and thought, its presence had become split among many—some lesser, some greater—each connected by a fleeting arc of consciousness. Struggling to suppress its own disunity, Zet sped toward the burgeoning conflict of its siblings, bending its fractured wills toward a singular conclusion: the aspects of the primordial mind must be made to reunite, or all must be destroyed lest the conflict spread further…

[edit]Trivia
[edit]- Arc Warden was first teased on day 3 of the New Bloom 2015 update page, where he is frozen within a glacier. His head, a shoulder pad and hand are partially visible.
- After being teased in the update that officially added Winter Wyvern to the game, he ended up being the next hero to be ported over from DotA.
- Arc Warden's kill response ▶️ "You will just have to accept this, and move on." is a reference to a Dota 2 based web cartoon "The Dota 2 Reporter", where it is a recurring gag for the characters to question the game's logic, only to be answered by this line.
- A lot of Arc Warden's lore and responses reference the work of the psychiatrist Carl Gustav Jung.
- Arc Warden's focal point of unification is based on the psychological concept of individuation. Put in simple terms, in Jungian Psychology, the concept of individuation is when the conscious ego combines with the unconscious shadow, creating "the Self". Arc Warden exclusively refers to itself as "The Self". Tempest Double's concept also references this, with Arc Warden representing the conscious ego, and the Tempest Double representing the unconscious shadow. As stated in the ability's lore, Arc Warden despises this ability, since it brings disharmony; Arc Warden can only be The Self if not split apart.
- Some of Jung's work is also reflected in Arc Warden's abilities, like how Flux is only harmful when the target is alone, i.e. not united with their allies, or how Magnetic Field only works against enemies outside its area of effect. Spark Wraith's ability description also states that it affects its target by "fusing" with them.
- His rare line ▶️ "From the Primordial Consciousness all came. Return to it, all must." refers to the pyschological concept of the Collective Unconscious, which refers to the unconscious mind and shared mental concepts. This was also coined by Carl Gustav Jung.
- Warcraft 3 similarities:
- Arc Warden uses the model of the Gnoll Warden, a medium neutral creep.
- His attack lines ▶️ "Doggedly." and ▶️ "Hounding." are a reference to this, as Gnolls in Warcraft are humanoid canine creatures.
- His rivalry lines towards Lycan, ▶️ "Inferior form." and ▶️ "Apex predator, you are not.", are also a nudge to this.
