The Fireblade Clan chieftain Nirru was severely wounded by Amy again after his battle with Amy in Stormwind, and his clan withdrew from the Orcs strategy war against Azeroth. Niruel, who left Azeroth, returned to Norad to recuperate. At this time, the situation in Norad also changed dramatically. The orc expedition took away the super clans of the orcs, such as Blackstone, Warsong, and Frostwolf, and Norad became a leaderless state in an instant.

Half a year after Nirul returned to Norad, the Shadowmoon Clan once again conquered the remnants of Norad's orc clan to form a new orc tribe, and the chieftain of the Shadowmoon clan was none other than the former orc Great Shaman Naozu. The Fireblade Clan also lost a lot of combat power due to its participation in the invasion of Azeroth, and after being attacked by the Shadowmoon Clan, Nirul had no choice but to submit to Naozu.

As well as the Juggernaut, Nirru was also a member of Gul'dan's Shadow Council, and he has been a member of the Council to help Gul'dan in various assassination efforts. However, when Gul'dan betrayed the orcs, Nirru was also abandoned by Gul'dan. Nirru was furious, he had joined the Shadow Council because he believed in Gul'dan's ambitions, but Gul'dan had betrayed the orcs at the most critical moment. Later, he followed Orgrim in pursuit of Gul'dan, but they only found Gul'dan's body.

After returning to Norad and succumbing to Naozu, Nirru also lived quietly for a while. Until one day, the messenger of Naozu asked him to complete a mission.

With the defeat of the orcs who invaded Azeroth, a large number of orc clans returned to Norad, including the Warsong clan that had lost contact with the orc forces in Azeroth. The Warsong Clan, under the leadership of Grom, still reached the Dark Gate. By the time they arrived at the Dark Gate, they were unable to save the orcs from defeat, and the Warsong Clan was absent from the Orc's all-important battle of Blackstone Mountain.

Returning to Norad, Grom could not accept the defeat of the orcs, missing an important battle, and it was worse for Grom than death. He had always hoped that the High Chief at this time, Neozu, would be able to rally the orcs again to invade Azeroth. And when he found Naozu, Nerzu was standing next to his former acquaintance, the Talon Blood Demon. Grom also joined Neozu's command, as Neozu had once again rallied the orcs to become the High Chief in order to attack Azeroth once again.

The Dark Gate has been closed by the Alliance after the war, and the Orcs must reactivate the Dark Gate if they want to invade Azeroth, and the control of the Dark Gate is only in the hands of Gul'dan, and with Gul'dan's death, Naozu will not be able to reopen the Dark Gate. Just as Neozu was distressed, news came that the bone-eating orcs living on the Hellfire Peninsula, where the Dark Gate was located, had intercepted a group of Gul'dan's Warlock followers and obtained Gul'dan's skull.

With the Skull of Gul'dan opens the Dark Gate, and the Bone Eater Clan Chief becomes the target of Naozu. Most of the assassinations among the orcs were done by the Fireblade clan, and Neozu hoped that this operation against the skull of Gul'dan would be done in secret. Out of his own intentions, he didn't want the matter of Gul'dan's skull to leak out.

Before the orcs returned to Norad from Azeroth, the Black Dragon King Nesario had already made contact with Naozu. When Nao Aozu saw the special secret method of the black dragon, he was instantly subdued by the strength of the black dragon. Compared to spells, the Black Dragon Secret Method is many times more powerful, and Nao Aozu also obeys the words of this powerful Black Dragon.

Naozu has been worrying about his life and soul because he has been deceived by the archdemon Kilgardan. The Orc Clan reveres force, while the Shadow Moon Clan of Nao Zu is a shaman-dominated clan that is suppressed during the Orc Clan Struggle. By chance, Naozu discovers the existence of the Great Demon Kil-Gardan, and he trades his soul and potency for power from the demon. Gradually discovering that the demon had deceived him, he became terrified of the power he had gained, and unilaterally broke away from the demon.

Naozu had been trying to escape to a place where demons couldn't find him, and the appearance of the black dragon gave him a glimmer of hope. The Black Dragon told him that if he found the Scepter of Sargeras, the Book of Medivan, and the Eye of Dalaran, he could open a portal to any place in the universe.

The Black Dragon also told the exact location of the three treasures of Naozu - Azeroth. And finding these three treasures is the real reason why Naozu wants to open the door of darkness.

As the messenger of Onezu, Grom found Nirru, and he naturally respected Grom, a super soldier of the orcs. However, he didn't want to get involved in Azeroth's affairs at all, he just wanted to stay in Norad's quiet life, even if he lived a life of lack of resources.

However, the clan chief must remain loyal to the Great Chief, otherwise he will betray the orc tribe. After hearing that the mission was to retrieve the head of the traitor Gul'dan, Nirru agreed to Grom's request after a struggle.

This time, Grom was in the dark in Minilru, and went to ask the Bone Eater Orc Chief Harkan Skullsplitter for Gul'dan's skull. When negotiations with Halkan did not go well, Grom and Nirru had no choice but to kill Halkan and forcibly seize Guldan's skull, and take over Halkan's Bone Eater Clan.

With the help of Talon Blood Demon, Neozu, who had obtained Gul'dan's Skull, quickly mastered Gul'dan's method of manipulating evil powers, and the Dark Gate was opened again.

In the 8th year of the Dark Gate, the Third Orc War began.

The orcs who came to Azeroth again were quickly overwhelmed by the Alliance, and the defensive front with the Watchweek as the core surrounded the three layers inside and outside the Dark Gate, and the Orcs were bombarded back by the Alliance with cannonballs and arrows before they came out of the Dark Gate.

And this made Nao Zu very happy, he finally had a legitimate reason to go and directly grab the three magic weapons he really needed.

Soon, the task of infiltrating the theft fell to the Fireblade clan once again. Naozu arranges for the Orc Legion to attract the attention of the Alliance to the Fireblade Orcs at the Dark Gate, while the Orc Swordmasters need to steal magic weapons from the rear of the Dao Alliance. Such an operation was naturally planned by the black dragon Nesario, who told all the whereabouts of the three magic weapons to Naozu, and would help Naozu when he acted.

With the help of the Black Dragon, Neozu soon gained the Scepter of Sargeras. Under the raid of the Black Dragon, the Fireblade Orcs also stole the Eye of Dalaran from the rebuilt city of Dalaran. The whereabouts of the last artifact, the Book of Medivan, have been determined, and the Book of Medivan is on the human mage Khadgar. Khadgar was leaving alone for the Kingdom of Quel'Salas to attend the wedding of his brother Amy.

The task of intercepting Khadgar fell to the orc chieftain Nirru, and although Nirru did not want to accept this task, the other sword masters of the clan had already joined the war, and these clan compatriots had also become hostages in the hands of Naozu in disguise.

Nirru ambushed Khadgar in the woods of Dalongmir, before the news of the Dark Gate's reopening reached Khadgar's ears, and he had just left the Watch Castle guarding the Dark Gate to attend Amy's wedding.

The orc raid caught Khadgar off guard, and after a battle, he was defeated by Nirru. Khadgar is injured and unconscious, and Nirru finds the Book of Medivan on Khadgar and leaves, and Nirru spares Khadgar as if he had been let go before.

After being wounded and unconscious, Khadgar was sent to the royal city of Lordaeron by passing civilians. Khadgar is the hero of the Alliance, and this incident naturally alarmed King Terenus. Khadgar was under Lordaeron's full care, and Khadgar soon woke up and told Tyrenus about his attack by the orcs, and soon after the news of the orc's return reached Lordaeron.

Khadgar checked and discovered that the Book of Medivan had been snatched, and the orcs were unable to break through the defenses of the Dark Gate, and Khadgar soon had a bad premonition. The orcs were about to reopen a portal to Azeroth, and the news of the loss of the Eye of Dalaran convinced Khadgar that the Eye of Dalaran was the basis of the Dalaran Portal.

If orcs invade Azeroth through portals other than the Dark Portal, the Alliance will become undefendable. Realizing the seriousness of the problem, Khadgar dragged his badly injured body and flew directly to Quel'Thalas. I'm sorry for Amy, but Azeroth's survival is more important, and he needs Amy to follow him now to get what he lost.
