Itarim of Dimension-1

When this Outer God first leaned through the Void Gate toward the planet, what mankind glimpsed against the sky was a single, immense eye. That floating gaze became the only form the entity revealed to the world below, a presence so vast and undeniable that no one who saw it questioned that a true deity had turned its attention on them.

Having endured across an unimaginable stretch of time, the Itarim has watched whole universes spark to life and dissolve back into emptiness, leaving it numb to nearly everything. Most of existence registers to it as dull and pointless. Even so, the god is not wholly without spark, and a thread of curiosity survives the boredom. For an entity this jaded, labeling something interesting functions as its highest praise, a thin form of regard it almost never extends.

For ages the god stayed shut inside its own realm, treating the things it created as private entertainment. That routine cracked when a fugitive from elsewhere, a Demonic Spectre named Kandiaru, slipped into its territory begging to serve. The deity brushed off the pledge at first, but Kandiaru bought his place by handing over a revelation: in his home universe, the Absolute Being had been struck down by the very life it made, leaving that realm divine ruler and overflowing with untapped mana.

Being the first of its kind to hear of that abandoned, power-rich cosmos, the Itarim moved fast to seize it. The maneuver could not stay hidden. Once its kin caught wind of the forsaken realm, the Outer God War erupted, pitting the Outer Gods against the Rulers and against the Monarch of Shadows. Each god sent Apostles to slip onto Earth and raise a Gate linking back to the Outer Universes, so its master could cross over. For its own bid, the Itarim of Dimension-1 deployed a fresh Apostle, Kanderiu, to do the work.

During the North Pole campaign, that Apostle, Kandariu, quietly took over a fitting vessel: Yuri Orloff, an S-Rank Hunter whose mana barriers shielded Russia from beasts and who carried real political weight. Hidden inside him, the Apostle steered Yuri toward an obsession with matching divine power, nudging him to engineer circles that could filter the lethal energy of the Outer Universes through his body. That secret effort became Project Unwithering Spring. Yuri thought the Void Gate he opened tapped a wellspring of godly strength, but it was a bridge straight to the Itarim's realm.

As the gate widened, the seer Norma Selner felt the intrusion and saw the god's hostile intent in a vision. She warned Sung Suho, by then the ascended Monarch of Transcendence, and when he looked back through the link the deity returned his gaze, amused rather than threatened, before Norma cut the connection. Despite the resistance of Suho and Thomas Andre, the god was summoned over the North Pole through Yuri's sacrifice. Free at last to act on Earth directly, it fixed on Suho, called him interesting, and projected its nightmarish domain across the sky for all humanity to behold with the naked eye.
