The Itarim's role in Solo Leveling and the Ragnarök sequel

The Itarim play a heavy and dangerous role in Solo Leveling and its sequel, Solo Leveling: Ragnarök. They are ancient entities, older than the worlds they created. They molded thousands of realms for centuries, but boredom became more powerful with each passing era.
Creation itself was no longer enough. They entertained themselves by having their creations battle one another indefinitely. It was emptiness giving rise to cruelty, and it changed everything in the universe they once shaped.
Their true involvement begins with the Monarchs' death. One of the Itarim was killed by his own forces, and none of the other Itarim cared. They saw the situation instead as a challenge. They decided to conquer the world he left behind because it was rich with lucrative mana deposits.

For this, they dispatched the Apostles, their dedicated though ruthless slaves. These Apostles were commissioned to pursue the source of the mana, causing a great war to erupt.
The Rulers soon realized that there was an invasion. They joined together against the Apostles, but the war was brutal. Each Apostle who had died was succeeded by another one. Unlike in the past, the Rulers could not get stronger. Their powers had been rendered useless as a result of the destruction of the Absolute Being.
They fought fiercely, but a victory for them seemed impossible. That was until Sung Jinwoo intervened. Employing his ability to summon shadow soldiers, he provided the Rulers with an opportunity to fight back.

A bloody war ensued, but a few Apostes still found their way into the human world. This sent the Rulers into a panic. They argued about whether they should fight humanity themselves, but they did not want to divide their army.
Defending humanity would mean they could be defeated. In this desperate situation, Jinwoo made a fateful decision. He broke the seal on his son, Suho, so that he could fight. He also returned Beru, a loyal friend, to guard Suho and lead him.
The Itarim's powers and abilities, explained

The Itarim have abilities that put them way beyond any other creature in Solo Leveling. They are world creators, constructing entire universes with mere will. Their power to create is not bound by size or laws. They can effortlessly create intricate worlds teeming with life, magic, and whole civilizations.
The other prime talent they possess is the awareness of dimensions. The Itarim can see through various worlds and realities. No world is hidden from them, not even those forsaken by other gods.
Theirs is the sight that breaks through barriers that mortals would be incapable of overcoming. It guides them to find possibilities, weaknesses, and even potential threats across endless realities.
Final thoughts
The Itarim are elder ancient who created worlds and presently threaten to do so in Solo Leveling. Their presence is not random or simple. They are powers of both creation and destruction. They grew bored of peace, creating infinite wars in their creations.
Their desire for mana resulted in chaos upon the Monarchs' downfall. They possess powers, such as world creation and sensitivity to dimensions, that make them almost invulnerable. They are not something that enemies can easily fight. The Itarim forever altered the path of Solo Leveling with their presence.
