Odyssey of the stellar wind, [Honkai Star Rail x Hoyoverse fanfiction]

Rex, the atoner of the Stellar winds,

The enemy has been defeated, the world has been saved. 

The hero that saved the world was rescued and the villains were defeated. 

All is well as life moved on,

All other than him,

The Archon of Anemo. 

Following the footsteps and path of his great grandfather 

The Anemo Archon reached the imaginary tree, freeing his beloved friend from the choice (prison) she had made. 

All for the sacrifice of his entire existence. The existence or memory of Rex Crozzo has been erased in his original timeline but it is a better alternative to having his dearly beloved friend sealed away forever. 

"Where am I?" Rex asked, looking at the Snow-covered land by himself. His black suit with a lone white sleeve protected his form as he looked around. 

"Halt!" A masculine voice said and the Anemo archon move quickly. Grabbing something from the air, the young man pulled out a sword made of condensed winds, invisible to anyone but him. "Who are you?" 

Saying nothing, Rex looked at the blonde-haired man in front of him. His cyan-green hair danced in the cold winds of Jarilo-VI while his black suit with a white right sleeve and the blue sash over his suit danced in the wind. One move and he could kill these guys. 

"Rex, Rex Crozzo," Rex said as he looked at them, standing regally as he stood with the aura of an Archon. How ironic, the man that sold the world to save someone... "Where... am I?" Rex asked as he looked at them. 

"You don't know?" Before the man can react, he was face to face with the hypnotic cyan green eyes of the archon 

"Can you be a good guard and give me clearance?" The archon said with a smile as the blonde-haired guard's eyes widened until he stopped moving. 

"Of course, sir," the guard said with a smile as he and the others escorted the archon. 

Rex sighed as he was escorted by the guards. 'How ironic that manipulating people like him would be my most useful skill,'

It has been a month and the former archon and successor of the overseer had easily melded into the civilization of Belobog. Some blackmail here and there, some favors and jobs and done. the young man sat in his office inside the Qlipoth fort. The young man wore a variation of his archon suit, well it was one of his few vices since there are no video games in Belobog or something. 

"What do you want, supreme guardian?" Rex asked, stopping his paperwork as he saw the door to his office open to reveal this world's version of Cocolia. He had impressed the supreme guardian and he was granted this job. 

"Still working hard, inventor Crozzo?" Cocolia said with a smirk as she approached his desk. 

"Yes, I need this job to get money," Rex said as he set the pen down before staring into her eyes. "What do you want?" 

"I need you to help the commander of the Silvermane guards to reestablish connections with the underworld," Cocolia said with a smile. 

"I'll pass, coordinate with someone from the underground," Rex said as he looked at Cocolia. "I'm busy containing the Stellaron," 

"Really?" 

"I'm not going into politics, Cocolia. I'm a sol- Inventor," Rex said as he put his pen down.
