After leaving the portal through Medivan, Dia went straight to the ruins of Lordaeron's Royal City, where she was besieged by a large number of undead when she first appeared.

Just as Dia was about to cremate the undead, he heard an unexpected voice.

"Dia, why are you here?

After the voice came, the undead who surrounded her spread out a passage, and Hina in the undead state appeared in front of her. Although she knew that Sheena had become an undead, she was still a little shocked to observe the transformation of an acquaintance at such a close distance.

"Amy said you need people to deal with the undead, and asked me to come and help. Are these the legions of the undead you control?" said Dia.

"Well, during this time, as Kel'thugad attacked on the Psychic Tower, my legion has grown a lot. These are the undead under the control of Arthas. Sheena said.

"Lord Sylvanas, who is this human?"

Behind Sheena, a human knight rushed over.

"Well, she's our helper, let's go back to the Undercity first. Sheena said.

The knight begins to lead the army of the undead towards the Undercity, and Hina arrives at Dia's side.

"Here I can only be Mr. Undead, otherwise there is no way to rule over them. Dia, don't see you. Sheena whispered in Dia's ear.

"It's okay, how many years have we lived together. How could I be angry about something like this. But are you going to stay here like this in the future?" Dia asked.

"It's a state of war now, and that's all I can do. There's nothing to do in the future, I can come back to you as an elf, and I'll just leave the matter to my lieutenant here. They are directly controlled by me, and even if I turn back into elves, they will not betray me. Sheena said.

"That human knight is also your lieutenant?" Dia asked.

"I picked him up near the Scarlet Abbey, and when I found him, he was almost lifeless, and I could only infuse him with some death energy to bring him back to life in a half-human, half-undead state. But it's also someone who has something to do with us. Sheena said.

"Anyone related to us?" Dia asked, confused.

"He was the second son of Alessandro Mograini, the former commander of the Lordaeron army. Amy and I were the Alsace they were resisting when we were on Kalimdor. Sheena said.

"I know this, it was they who asked for help in the first place, and I asked Gianna to find you. Dia said.

"The elder General Mograini did not die at the hands of the undead, but was killed while chasing his eldest son and adopted daughter who eloped, so his second son has been seeking revenge. His brother was in the Scarlet Monastery, but it was now under his brother's control, so he had been taking revenge without success, but was seriously injured by his brother and escaped from the monastery, and was saved by me. Sheena said.

"If it hadn't happened like this, Lordaeron's defense line wouldn't have collapsed so quickly, and General Mograini would have been a pity. And you're helping him get revenge?" said Dia.

"Now that the undead of Kel'thugad are constantly at war, I don't have time to bother with these things. There's a meeting later, so come with me. Sheena said.

"Meeting, what meeting?" said Dia.

"There are now three forces of our resistance to the undead of Kel'thugad, one is my Legion of the Forsaken, one is the Silver Dawn, and one is the Kingdom of the Sindore Elves. There will be a battle meeting in the Undercity. Sheena said.

"It's nice that you've learned to form alliances. Dia said.

"There are too many undead brought by Kel'thugad this time, and they are completely unable to fight against it alone. So we had to form a united front first. Sheena said.

While talking and talking, Sheena and Dia have arrived at the ruins of the royal palace in the royal city of Lordaeron.

"Darien come with me, and the others go back underground first. Sheena said, glancing around.

"Underground, you built an underground city?" Dia asked.

"Most of the undead don't like sunlight, so they built an underground city of their own, which I had already built by the time I returned. However, today's meeting will not be scheduled there, so we will go to the site of the original royal palace. Sheena said.

The entire royal city of Lordaeron was completely destroyed after the fall of Arthas, and although it is now a dead city, it was cleaned up after it was taken over by the Forsaken Legion. Although there was no way to repair the damaged buildings, the corpses in the city were either their companions or their lunch, and the current ruins of the royal city were of acceptable standards.

Outside the halls of the old palace, Uther had arrived early. Although he is no longer human, everything here still fills his heart with regret. And after seeing Darian, he was immediately a little excited.

"Sylvanas, how did you turn him into this?" Uther immediately questioned.

"It was the Queen who saved me, Lord Uther. I went to my brother to take revenge, but I was injured by him instead of being able to do so, and when I was dying, the queen saved me and took me in. Darien said.

"Uther, he's only half an undead, and he's close to you in state, so it's better for you to take him in. Sheena said.

"Would you like to join the Knights of the Black Blade? Uther asked, looking at Darien.

"I just want to avenge my father, and I can join anyone. Darien said.

"That bastard of Renault, if it wasn't for him, our defense line wouldn't have broken down easily. I can help you with your revenge. Uther said.

"Thank you, Master Uther, then. Darien said.

"But the object of your revenge can only be Renault, not indiscriminately killing innocents. Otherwise, your revenge is killing. Uther said.

Darien nodded.

"Kneel, child, and I give you the power of the Blackblade Knight. Uther said.

Darien immediately knelt on the ground and was sealed like a normal human when he was promoted to knight, but as Uther's ritual progressed, Darien's body began to circulate with black lines, and the death energy in his body began to grow stronger. Eventually, he became a Blackblade Knight similar to Uther.

"Your weapon is your father's Ember Bringer, right?" said Uther, looking at the greatsword that Darian was carrying.

"Yes, it hasn't left me since my father died. Darien said.

"I'm afraid it needs a new master, and our current state is no longer able to draw out its Light energy. Abydis and Tulayan are coming in a moment, would you like to sacrifice this weapon?" asked Uther.

"Of course, this weapon can't live up to his prestige with me. It is more suitable for a warrior who truly believes in the Light. Darien said.

Just then, Abidis also arrived in the palace hall with the Silver Dawn Man, but an unexpected person also appeared in the group. He was Tirio Fortin, who had been demoted to a civilian for helping the orcs, and after the old knight was demoted to a civilian, everyone thought he was dead because there was no news of him.

"Uther, it's been a long time since I've seen you come first, and you've really become like this. When Fording saw Uther, he immediately sighed and said.

"It's good that you're alive, otherwise our first five knights are really only Tulayan. Uther said.

This is Tulayan, who also dismounted and walked towards Uther.

"I'm sorry, I'm done coming back, and it wouldn't have been like this if I had come back sooner. Tulayan said.

"I'm relieved to see you and Aurelia back safely. As long as you are still in the Silver Hand, there will be no real death in the Knights. Uther said.

This was the first time Tulayan had seen Uther since returning to Azeroth, and it was also the first time Aurelia had seen her undead sister Sylvanas.

Although Aurelia looked at Sylvanas with a heartbroken expression, Sylvanas looked at her sister's gaze very calmly.

"Dia, is this bastard Amy here?" asked Aurelia.

"No, are you looking for him?" said Dia.

"It's nothing, I want to teach him a lesson. Aurelia said.

"Aurelia, don't mess around, we're here today. Tulayan said quickly.

"He's not here, and you don't want to touch him when he's here. Sheena just said coldly and walked away.

"Don't worry too much, Sheena's affair is quite exciting for herself and Amy. Let's not get too involved. Now Amy is still working on other things. Dia said.

"Now that the undead are back, what else does he have to deal with?" Tulayan asked.

"I just came out of the Emerald Dreamland, and now Azeroth faces a threat from the Old Gods. The problem of the undead is left to us alone. Dia said.
