Kel'thugad, in the original stream of time, was the culprit behind the undead scourge wreaking havoc in the kingdom of Lordaeron. This mage of Dalaran finally left Dalaran angrily after being repeatedly prevented from studying necromancy by the Kenrito Council. And at this moment, a mysterious summoning from Northrend, the far-flung Far North, drew the necromancer to the Frozen Throne.

After seeing the Beetle King of the Eldrunirub Kingdom, Anubrak, who had come back from the dead but still retained his memories and consciousness, Kel'thugad believed that the Lich King Neozu could fulfill his wish to bring the dead back to the world of the living, so he took complete refuge in Neozu.

Kel'thugad, who returned to Lordaeron, became cold and cruel. He mixed a plague poison supplied by Naozu into the barns of Andorhar and succeeded in transporting the contaminated grain to various cities north of Lordaeron. This plague can transform living people into unconscious, fearless zombies.

Although this necromancy is not in line with Kel'thugad's original intentions...... But he didn't care, as he had emphasized many times, the black-robed mage had no concern for the fate and future of the human race. Although Arthas succeeded in killing Kel'thugad as a human, it was not long before Arthas, who had been completely controlled by the Lich King Neozu, resurrected Kel'thugad and turned him into an immortal lich. ,…,

Although Arthas had already pulled out the Frost Sorrow at this time, the little magic sword was not yet fully conscious. As Arthas and Kel'thugad led the undead army around, Frostmourn finally awoke from his slumber and had his first conversation with Arthas.

The turning point of a qiē all began here. Before this conversation, Arthas had almost completely lost consciousness of himself. Became the Lich King Nao Zu's killing machine. However, Frost Grief lightly broke the spiritual link between Naozu and Arthas, allowing Arthas to regain his consciousness.

The rest of the story can be imagined, after realizing that he has committed irreparable mistakes, Arthas is bent on killing himself. However, like a newborn baby with an inexplicable affection for the first person she sees when she opens her eyes, Frost Sorrow does not want Arthas to die like this, so she calls Kel'thugad.

Kel'thugad, who had already turned into a lich, was not obsessed with the fact that Arthas was no longer subordinate to the Lich King Neozu. After defecting to Neozu, Kel'thugad has been fighting for the Scourge Legion, but this is not the result he wanted. After a conversation with a grief-stricken Arthas, Kel'thugad succeeded in convincing Arthas and gave him the motivation to continue his life by taking revenge on the Lich King Neozu. and to atone for their sins by resurrecting those who have died. ,…,

Aside from the small episode in which Sylvanas was shot by an arrow from the arrest, Arthas and Kel'thugad's plan went very smoothly. With Frostmourn's near-godly ability to control souls, Arthas replaced Neozu as the new Lich King. Soon after, Kel'thugad transferred the "Sky City" Naxxramas to Northrend, completely abandoning the Eastern Kingdom and concentrating on working with Arthas to study the necromantic magic that can truly break the boundaries between the living and the dead.

Among the necromantic magic mastered by Arthas and Kel'thugad, there are many ways to make the undead who can get back on their feet have memories of their previous lives, but there are various limitations. The Lich may be the perfect of these methods, but this method of resurrection is limited to mages who use arcane arts.

The banshee, represented by Sylvanas, is in the other direction. However, this method is not suitable for other races, not all races, like the High Elves, even those who cannot use magic have a natural affinity for arcane. …,

Before Neozu became the Lich King, his disciple, Gul'dan, used an extremely filthy/evil necromancy - filling the souls of dead orc warlocks into the corpses of human warriors to create a magical warrior with independent consciousness - the Death Knight. Kel'thugad has just met Tyrone Bloodseeker at Dunhold Castle and is the first Death Knight ever. ,…,

Although this method has its limitations, after numerous failures, Arthas and Kel'thugad have finally made progress, successfully summoning human souls back to their original bodies, creating a new Death Knight. This kind of death knight, was seen as hope by Alsace and Kel'thugad, because in the process ...... The dead don't have to be able to use spells, so this method may be generalizable to all the dead.

However, behind the great hope often lies an abyss that cannot be crossed. Alsace and Kel'thugad soon discovered that this approach, while somewhat less limited, was not always successful. After many experiments, Arthas and Kel'thugad despaired that anyone who could be resurrected as a Death Knight had to be a warrior or paladin in his lifetime. Only by having a strong body and a resolute soul at the same time can you have the memories of life after coming back from the dead.

Arthas still vividly remembers Kel'thugad's actions after discovering this conclusion, albeit as a lich. Kel'thugad's head had completely turned into a skeleton, but the eyes that had been glowing blood-red had dimmed in an instant. ,…,

"No...... Don't ......" Kel'thugad's chained body took a few steps back, his sharp voice full of despair, and his hands were placed on his chest, where Arthas knew, and there was a small iron box. Every lich will have a soulbind box, which is necessary for their rebirth. However, what Kel'thugad had in his chest was not his own Soul Binding Box, but the urns of the Lich's own parents.

Kel'thugad was born into a family of farmers in the hills of Hillsbrad. His parents had only one son. When Kel'thugad was allowed to learn spells in Dalaran because of his outstanding talent, he was still a young child. In the beginning, Kel'thugad's life in Dalaran was very glorious, and his talent allowed him to leave his apprenticeship and become a mage in just a few years.

At the age of twenty-seven, Kel'thugad became an alternate member of the Council of Six of Kenrito, nominated by Gianna's teacher, Antonidas. However, just as Kel'thugad was in the midst of his triumphant spring, bad news came from his hometown, his father died of a sudden illness, and his mother passed away due to excessive grief.
