"Rex... what do you mean the amber throne is your prison?" Welt asked as he looked at his nephew. 

"Guizhong, Uncle Welt..." Cerberus said as he took out a cube, the same cube he was working on a few viewings ago. "Everyone, I want you to try and open this," Cerberus said, setting the cube down on the ground.

Silver wolf raised her brow as she looked at the cube in interest. She and the other Stellaron hunters were in a hidden part of the theater.

"Let me just," Cerberus said as he bit off a part of his skin and poured a drop of blood on it, "Activate, amber throne," 

Nothing happened. Yet, the cube throbbed as if it was a living heart. slowly but surely, it harmonized itself with the pocket dimension of the Archon hall and it happened faster than light. 

"do it," Cerberus said as he presented the floating cube to them. 

"Interesting, Silver Wolf," Kafka said and before she knew it, the hacker had already appeared near the former archon. 

Welt focused on the cube as he looked at it, ignoring everything as his mastery and status as the 2nd Herrscher of Reason allowed him to analyze the beating heart of the cube. Amazed at how alive it felt, it was only then that he realized it. The beating of the heart instantly synchronized with his ability, harmonizing it. 

Sweat fell from Welt's forehead along with Guizhong as they analyzed the cube. Even Cloud Retainer, in her human form, stumbled at the sheer engineering. 

"It's singing..." Silver wolf whispered, mesmerized by the cube. 

"Tonal architecture of the Dwemer, the scientific wonders of the age of technology," Cerberus whispered in a trance-like strength as he flared a bit of his Power that instantly became comparable to that of the Herrscher of Finality's weakest feats. 

Silver Wolf smirked in nervous excitement as she looked at the cube. Herta and Asta looked at the cube as they began to Analyze it. "Originally, I had intended for it to allow me to raise my affinity with the element of geo, but an accident made me realize how I should fear my status as both an archon and herrscher." 

"This is only a prototype and contains only a fraction of the original amber throne's complexity," Cerberus revealed as he handed them the cube. "This is the Amber Throne, type S," Cerberus said. "In my madness and research into the Void Engine, this allowed me to find out about the Multiverse," 

"Then," 

"Yes, Uncle Welt. The amber throne is created from the accumulated knowledge found throughout the numerous worlds of the multiverse with the help of the Amber Throne type B to gather data and for type H to run the simulations, I used the type Neo to other imaginary trees with the help of the knowledge and theories I made based from Skyrim's tonal architecture." Cerberus said. "The black boxes are the key to my throne, I scattered them on earth and the last one is being kept in the golden throne of my dear friend, the emperor of Mankind. But to make sense of why I did this... Reena, can you play it and take the children away?" 

"I will," Reena said as her eyes glowed. 

"Finally!" The voice of Kiana Kaslana echoed in the entire theater as she and Bronya appeared in the theater room. "I told you that using his theories in his journals can help us." 

"Yes, yes, Kiana Idiotka. I missed when you were the dumbest one of all of us," Bronya quipped with a dramatic sigh.

"You're just jealous that I didn't," Kiana turned around as she saw Reena. Feeling the familiar hum of Finality in her, she looked around and saw him. Her best friend, holding onto one of his Black boxes, now renamed amber thrones. Tears fell from her eyes

"Wendy!" Rex shouted as he lowered his bow and cradled his girlfriend in his arms, she was heavily injured and they knew she was dying. 

"Rex..." Wendy whispered as she reached for his face. "Ah... I'm so glad..." 

"Stop talking!" Rex begged as he scrambled for the strips of paper. "Adeptus art: Harmonious resonance," 

Rex in the theater winced as he remembered the domino that started it all but said nothing as he sealed his emotions away. 

"I... love... you," Wendy said with tearful eyes as she smiled at him. "Ah... I'm so glad..." Rex heard her but he focused on one thing. He wanted to save her. He needed to save her-

Bang!

Just as the element she wielded, the successor of the Anemo archon, his girlfriend, disappeared like the wind. The last thing he saw of her was the hole in her head. 

"You BASTARD!" Kiana roared as the authority of finality erupted from her, all those that felt it fell to their knees. Cerberus managed to shakily stand up as he held the amber throne prototype. 

'See, you and your family fought for them for countless generations, for 50 thousand years,' a beautiful seductive voice similar to Wendy's echoed in his mind.

'No... it's not... must not,' Rex thought as his seal on the Gnosis slipped, allowing countless memories of the battles and atrocities that Rex Lapis committed. Blood, too much blood covered his mind. It was cold.

'See, let it go.' the voice whispered once again as the gem of the stars formed in his hand. 'Wanna dance with me, Rex?' the voice said in complete imitation of Wendy

The sheer audacity made those that knew Rex or Cerberus feel anger and hate for the voice, doubly more for those that knew Wendy. 

Kiana wasted no time and hugged Cerberus in her arms, trying to give him as much comfort but she was too late. The former archon had retreated deep into the recess of his mind, meditating to control himself. Yet, the simple hug from Kiana brought him back and he smiled at her. 

"AHHHHHHHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!" Rex howled in primordial rage and anguish as the entire world he was in on another reality moved. Twisting and turning as his enhanced affinity to the element of Geo and the awakening of his Herrscher self. At the same time, his entire being harmonized itself with the world

The celestial bodies and entire satellites rapidly moved, forming patterns upon patterns similar to circuits. 

Once Rex came to, his eyes widened as he saw the void. The entire solar system of the reality he was in was replaced by nothingness and a black hole that resembled an eye. No... that black hole used to be the world. 

Looking at himself, the young archon saw that his dark hair turned to the same shade of gold that Otto has, and his combat uniform was replaced by a pure white suit. Despite the void of nothingness that surrounded him, the stars still remained 

Silence appeared as even the gods of Teyvat to the Herrschers and Stellaron hunters could not believe what they saw. An entire solar system was erased to nothingness at the awakening of the archon's Herrscher self. 

'Good. Very good,' Wendy's voice distorted as it chuckled. 'See, you are only the ninth and you accomplished what the others didn't fifty thousand years ago.' 

Tears fell from Rex's eyes as his mind went into overdrive as he analyzed the situation. 

'And it was all thanks to you. I hereby name you, Herrscher of the cosmos,' the voice whispered in a distorted motherly tone as tears fell from Rex's eyes. 'You already finished your duty. A contract is a contract. I will manipulate you no longer. Fare well, Cosmos,' 

The voice disappeared leaving the new Herrscher of the Cosmos a maddened mess as he laughed and cried in despair. Suddenly, the Archon stopped laughing as he slicked his hair back as motivated madness burned in his eyes. "Honkai..." he growled out in a deranged yet serene snarl. 

"This is the reason why the Amber throne is complicated," he said, "It is meant to contain my volatile madness and was originally meant to be a suicide weapon but I altered it when I found hope," 

Cerberus said as he remembered the shining ray of light during his dark madness. 

Slap! 

Kiana slapped him hard. "That was for disappearing on us and not telling us about this. And this is for being alive" Kiana said with a smile before she pulled him by his collar and kissed him on the lips in full view of everyone.
