Above the heavens of the Valoran Continent, the leaders of the Void Creatures stood silently, and they looked at the extremely large Valoran Continent below them with an unknown meaning in their eyes.

At this time, in the vicious place at the western end of the Valoran continent, Shadow Island, a man wearing a black cloak covered his face was quietly hanging in the sky above the Shadow Island.

The man who didn't see his face seemed to say to himself: "Although I don't want to see this world, that's also my business, and it's not your turn to point fingers at you insects."

His name was Karthus, and he was a god-like being of the Shadow Isles, though his followers were still accustomed to calling him the Death Singer.

Karthas is the messenger of annihilation, the undead spirit. I have never seen its terrifying figure, and I have heard its ghostly elegy first. The living fear the spirits of the undead who will never be able to transcend life, but Karthhas sees only beauty and purity in the presence of the undead, and he sees the perfect fusion of life and death. When Karthhas was reborn from the Isle of Shadows, he resolved to serve as an apostle of the undead and bring the joy of death to all mortals.

Kartas was born under the walls of the Noxian capital, at the lowest level of the slums. His mother died at the same time as he was born, leaving his father alone to raise him and his three older sisters.

They live with other families in a dilapidated almshouse with flies and squirrels, feeding themselves on rain and pests. Karthhas are the best foraging of all children, often adding some mutilated corpses to their cauldrons.

In the slums of Noxus, death is commonplace, and parents wake up to find their children stiff and cold, and a new day begins with their sobs.

Calthus slowly learned to appreciate these sobs and mourning, and he would watch with fascination as the death recorder of the Thousand Jue Order carved a counting mark on his cane before carrying the body out of the almshouse.

At night, the young Karthas would sneak around the crowded almshouses, looking for those who were dying, hoping to see the moment when their souls crossed into life and death. However, many years passed, and his night tour was fruitless, because no one could accurately predict the time of a person's death.

He never had a chance to see the moment when people died, until one day death began to visit his family. Disease outbreaks were common in such a crowded and dense settlement, and Caltha's sisters were also infected with the plague, so he began to take good care of them.

His father knew nothing more than drinking to kill his sorrows, and at this time Karthas became a dutiful brother, caring for and caring for his sisters when they were seriously ill and dying.

He watched his three sisters die one by one, and in their dying eyes, it was as if Karthas felt some kind of divine calling, he wanted to understand the afterlife, and he longed to explore the mysteries of eternal existence.

When the death recorder came to take the body, Karthas followed them back to the temple and kept asking them questions about the Order of the Thousand Jue and about the funeral work. Can a person exist in the gap between the end of life and not death?

If the boundary between life and death can be understood and controlled, can the wisdom of life be integrated with the clarity of death?

The Death Recorder soon found it a good fit for Karthas to join their Order and recruited him into his ranks, initially digging graves and collecting wood for cremation, and later rose to the rank of corpse collector.

Every day, Karthas would push his bone cart and store corpses on the streets of Noxus. Soon, all of Noxus heard of his requiem, and his eulogy was mournful and poignant, depicting the beauty of death and praying that the world after death would be a holy place to be desired.

Many grief-stricken relatives of the deceased will find solace in his grief and peace in the elegy. Eventually, Karthas was sent to the temple to take care of the sick, give them hospice care, and greet the dead when death came as expected.

Karthas would whisper to each person before they died, guiding the souls of the deceased towards death and looking for deeper wisdom after the blinding.

In the end, Karthas finally discovers that he can't learn much more from mortals, and only dead people can answer his questions.

While the dead soul can't tell him what the world is like after death, there are fantasy stories and legends used to scare children, about a place where death doesn't mean the end – the Shadow Isle.

Karthas swept away the money from the temple vaults and scraped together his money to travel to Bilgewater, a city that is haunted by a strange black mist that is said to pull people's souls towards the Cursed Island far beyond the sea.

None of the captains were willing to take Karthas to the Isle of Shadows, but he eventually found a drunken fisherman who was ruined by debt. The fishing boats sailed through the sea for many days and nights, and at last a storm blew them up an island that had never been marked on a chart, stuck on a reef on the shore.

A black mist billowed out of the twisted woods and barren ruins. The fisherman immediately pulled the boat out of the reef, turned its bow and fled in the direction of Bilgewater, but Karthas jumped out of the boat and waded onto the beach.

He barely stood firm on his scarred staff of the Death Recorder, and then proudly sang the elegy he had composed for his deathbed, his voice drifting into the heart of the island in a cold wind.

The black mist continued to drift away, passing through Karthas, ravaging his body and soul with ancient spells, but his desire to transcend death was so strong that not even the black mist had completely knocked him down.

Instead, the Black Mist reshaped him, and Karthas was reborn on the island's tidal flats as a disembodied ghost.

Karthas fulfilled his long-held wish and became the form of existence he had always dreamed of, standing at the junction of life and death, when he received a new revelation.

He was amazed by the beauty of a moment becoming eternal, and at the same time the other spirits on the island woke up, like a shark smelling blood, attracted by the enthusiasm of Karthhas to witness his transformation.

Karthas had finally found his home, and all the souls around him could grasp the true meaning of the blessing of immortality. A fervor of duty filled Karthas, and he knew that he had to return to Valoran to share his gifts with the other living, to free them from their trivial worldly worries.

Karthas turned, and the black mist carried him on the waves, catching up with the fisherman's boat. The fisherman knelt before Karthas and begged him to spare his life, but Karthas gave him the blessing of death, ending his worldly suffering and being reborn as an immortal ghost in the elegy of the dead.

The fisherman was the first of many souls liberated by Karthas, and soon the Death Carol singer would command an army of undead souls.

In the newly awakened senses of Karthas, the Isle of Shadows is in a state of ruthless Styx border, wantonly squandering the blessings of death. He wants to urge the dead to wage a holy war, to bring the beauty of annihilation to the living mortals, to end the suffering of the world, and to usher in the glorious age of the immortal.

Karthas became the messenger of the Shadow Isle, the spokesman of annihilation, and his eulogy extolled the glory of death. His legions of revenants will also join his requiem chorus, and their lingering songs will reach the confines of the black mist, echoing through the cemeteries and morgues of Valoran on a cold night.
