Kainath

is the creator of the Elves, and an Old Deus. Kainas is known as the God of Forest. During its reign of Elf during the war, Kainas positioned itself in an ever-spreading forest seeded from its Ether. As it used its Ether to protect the elves territory, to shield its population from the tolls of war, it was worshiped by the Elves as the true god in its natural stronghold.

Personality
Kainas considered its fellow deities foolish to oppose it stating them as "false gods" intending to use its creation the Elves to destroy the rest of them, and finally obtain the "throne of the one true god" in Practical War Game Kainas personally summoned and bestowed praise Think Nirvalen for her ingenuity and accomplishments and her loyalty to itself.

In addition, the location of the Akasha HQ, developing the "Akasha Hollowification Project" conceived by Think, was directly under Kainas's Sanctuary, which developed the Aka Si Anse Rite of Spirit breaking, utilizing a "Spell Furnace"

Surprisingly, Think Nirvalen's attitude towards the Kainas was very arrogant. She repeatedly denounced Kainas as an "incompetent god incapable of communication in any shape or form", "a useless windbag", "shitty", "a slightly more useful than confetti". In addition, the Rites of Spirit-Breaking developed by Think exploits the Ether of the Kainas as if it were firewood, almost to the point of lawlessness - but Kainas does not seem to care about these details, and it does not care about the feelings of its creations.

Strengths
As an Old Deus, Kainas is incredibly powerful being able to create an entire race.

Background
In No Game No Life: Zero, Riku Dola states it is one of the three most powerful Old Deus. During the Great War, the Elves had been ruled by Kainas, and Think Nirvalen and Nina Clive both having served as the "Grand Magus" respectively being directly responsible for directing the Elven Forces, planning Cities and controlling the flow of military information. However, after Tet announced the Ten Covenants, Think and Nina, split the elves establishing the nation of Elven Gard and vigorously promoted democracy, resulting in the gradual weakening of their creator's influence over the race, and was eventually replaced by the Elves complicated political factions. Today, about 6,000 years later, Kainas is practically no longer in charge of any affairs of the Elf race and is remarked to be a "grumbling old deus" Kanias Kanias
