The flow of geo in this world remains strong. The damage that humanity has created, amplified by the Stellaron, only ravaged the overworld, but not the planet itself. In an act of defiance, this world, Jarilo-V produced and modified its earth, allowing the remains of its children to live.

Geomarrow crystals, when processed, can be used as a source of heat. A gift of the planet towards its children. After all, no matter how cruel nature is, it will never willingly harm its children. That job belongs to the children themselves. 

'As the former archon of Geo, I have managed to amass an innate understanding of Geo,' Cerberus thought as he sat on crossed legs while expanding his reach to the entire planet. The mental map of the single living organism appeared in his mind as its beating core of a heart still moved while its unnoticed deposits of Geomarrow crystals resonated on their locations, begging to be used to preserve the lives of those that yet live. 

Preservation, the path that he walked, echoed in the very city of Belobog, humanity's last bastion. Gathering as much Geo energy as he could, a familiar cloth covered his shirtless form as the underworld's artificial lights bathed him. 

"What is it, Seele?" Cerberus said as the door to his room opened to reveal this world's counterpart to the gentle girl that he had befriended and the disappearance of his archon robe. Ironically, she was still the kind-hearted girl he had known. 

"How did you?" Seele started before remembering what she came here for. "Those are..."

 Scars, and countless scars littered Cerberus ' torso, and the most horrible one was the one on his chest where his heart should be. A circular scar that eerily looked like it was pierced by a lance. For a moment, Seele saw countless burn scars on his body. 

Realizing that the young man was naked in front of her, Seele turned red and slammed the door shut. 

"The fuck?" 

"Wooo! What is this place!" Blinking, Cerberus found his niece somehow using an amber-hologram version of Astral projection. Raising his brow, the young man harnessed the power of geo, draining a nearby Geomarrow crystal to form a long-sleeved white shirt. 

"A-are you decent?" Seele asked, peeking at the door only to see, a toddler-like amber-colored ghost looking around the room. 

"Is this your room? Whoa! It's super small! And it looks as bad as you!" Reese said with a smile while Cerberus wilted at how his niece roasted the shit out of him. "You know, Auntie Rin said that people that live in rooms like this are maidenless," 

A lance pierced Cerberus's chest, 

March, who was woken up by Seele, peeked at the door along with Stelle and saw how their enigmatic companion was brought to his knees by a toddler. 

"What are you three doing?" Bronya asked, looking at the three who were peeking at Cerberus's door. 

"Shhh..." March whisper-shouted while putting a finger over her mouth. "Look."

The future supreme guardian knew that this was a breach of etiquette yet she was curious about their enigmatic companion and she was not in the overworld...

Leaning in, Bronya's eyes widened as he saw the amber ghost-like figure of a toddler running around Cerberus's room. Cerberus was inside an amber shell while the toddler whacked his abode with a floating amber spear. 

How the toddler effortlessly carried that two-meter-long spear without problem was beyond them. 

"Stop that, Reese." Cerberus tiredly said as the amber shell shattered alongside Cerberus, only for the young man to reform from dust particles behind the toddler and picked her up like a cat. 

"No! Let me go! Stinky-Cerby!" The toddler shouted, squirming and trying her best to get out of the young man's hold but to no avail. 

"What are you doing here? And how the... How can you use an astral projection? It's only been a day since I gave you a quarter of my reserves," Cerberus said, looking at his niece. 

"Wait! No! I'm a ghost!" Reese shouted as she finally saw how ethereal she looked, causing Cerberus to wince. "I'm sorry Uncle Reve! I was curious about the balloon in your wallet and I poked it with a needle after you teased me!" 

Cerberus's mind ground to a halt. His hand loosened causing him to drop the astral projection of his niece. 

"Hey! Hmph! Now I won't tell you that I'll have a cousin. Bleh!" Sticking her tongue out and pulling at her eye, the astral projection ended, leaving Cerberus unresponsive. 

"I'm gonna punt that little gremlin as soon as I see her," Cerberus gritted out as he rubbed his temples, despite this, he felt pride as to how his niece managed to activate and resonate with her geo powers. "You four can come in, you know," Cerberus said, discreetly manipulating the door to open, causing the four to fall flat on the floor. 

"Who was that?!" March asked, crawling from the pile. 

"... my successor..." Cerberus said, omitting the truth about his niece. "Aren't you guys supposed to be asleep?" 

"Well, we got curious," Stelle said, getting up from the ground. 

"Who was that child?" 

"A gremlin called Reese," Cerberus said, sighing as he remembered how his niece did something that took him a few months to do. 

"And why aren't you asleep?" Seele asked, looking at the taller male. 

"I only sleep when I'm exhausted, Most times, I meditate instead of sleeping," Cerberus said, looking at them. "Though, I can't really fall asleep most times now. Too many dreams," 

"Wait how!?" 

"I'm awesome, that's why," Cerberus said as an image of a man appeared in his mind. The man with h/c hair reached in for the cube. 

"Found you," Obsidian orbs glowed ominously to a hauntingly beautiful pair of amber orbs. Raising his hand, a black rook chess piece appeared in his hand and before anyone can react, the chess piece disappeared in a bright light. 

Once the chest piece disappeared, the sweet and loving embrace of sleep welcomed the former lord of Geo as he passed out while standing. 

"Cerberus!" Seele shouted as she moved and caught the taller male. "He's fine, just exhausted," 

'thank goodness,' Stelle thought as she helped Seele put the male on the bed.

"Well, it seems like we can make do without him, tomorrow," March said as she poked Cerberus' cheek. 

----

Ah, you are finally here,

Gazing into the unknown, the former geo archon's eyes gazed at the amber lord. 

Obsidian eyes stared into the form of the amber lord. A single blade appeared in front of him, a double-edged sword with an amber blade. 

This path that you travel is yours alone. The loss of your Gnosis might have weakened you but it has opened a path. A path that only you can walk

========

Obsidian eyes opened as Cerberus found himself in the hotel. 

"So, You finally found them." The young man whispered as he looked at the replica of the gnosis in front of him. An artificial gnosis he has created, using his former vision as a base. "The contract has been fulfilled," 

Standing from his bed, the young man gripped his right wrist and eyed the symbol on the back of his hand. "Seems like the others have gone back to the overworld."

Eyeing his revolver, a small smile appeared on his face as he looked at his gray-colored pawn chess piece before closing his eyes. The pawn disappeared and went inside the young man and soon, a simple sword from Shenzhou appeared in his hand.

For the first time, the young man felt himself free. Putting his clothes on, the young man's eyes turned a bright shade of amber before his form disappeared into countless specks of amber dust. 

Tapping into the leylines, draining them to fuel his powers, the young man willed himself to reform beside a duo in front of a lot of monsters. 

"Total concentration breathing," The young man whispered. "Dark moon, evening palace,"

Several swathes of monsters were cut down in an instant as the former lord of Geo sheathed his blade. 

"Seems like, I'm too late to the party," Cerberus said as he 'saw' the giant robot on where the others were. "You guys okay?" 

Cerberus asked, looking over his shoulder to see the Silver Mane guards. 

"w-who?"

 Sighing, Cerberus slicked his hair back, obsidian eyes burning in intensity as he glared at the horde in front of him. 

"You guys stand back," Cerberus said as he fearlessly walked ahead of the group. 

"H-hey! Get back here!" Gepard said, wincing in pain as he tried to stop the former archon, only for his eyes to widen when an amber wall erupted and surrounded the entirety of Belobog. 

"It's been almost a decade," Ominous Amber tinted Cerberus' eyes, piercing the blizzard ominously as he raised his hand and a spear and shield formed in his hands. "Since I last fought!" 

With maddened glee, the former archon of Geo charged into the horde

The Silver Mane guards and Serval looked in awe as the former archon of Geo laid waste against the numerous hordes of monsters on his own. 

Smiling, Cerberus threw his shield and made it bounce, killing everything it hit before slamming his palm into the ground. 

"What? Is this your way of telling em how much you love me?" The woman with white hair and blue eyes said, teasingly holding the young man in a hug. 

"What? No!" 

"Well, if you want. You can name it after me! It can be your good luck charm!" 

"Moon breathing," The young man thought as his spear turned black before turning red. "seventeenth form," The spear of the young man moved as an intense amount of heat radiated from each movement of his spear. 

"Please!" The woman whined as she hugged the young man's waist as the others looked at the duo. 

"Fine! Just let go! I don't want to be killed by Mei!" 

"W-what!? I won't do that!" Mei Raiden shouted, looking offended that a dear friend of hers assumed she might kill him. 

"See, Mei-sempai agrees!"

"Tsukihime no Mai," 

All the guards could only watch in fear and awe as the former geo archon flowed seamlessly between 16 different forms, not once did his feet leave the ground for more than a second but it was enough.  No one saw it but as he stopped, tears fell from the former archon's eyes. 

"Rex! No! You promised!" 

"Kiana, I love you," 

"So, that was her name," The former archon whispered as he dissolved the writhing corpses into specks of amber dust, storing all that he collected in his false Gnosis. Wiping his tears away while disintegrating his amber spear, the former archon turned around and towards the city of Belobog with a stone-like face.

His obsidian eyes scanned everything and as soon as he entered the settlement, the barrier surrounding it shattered before being absorbed by the former archon as he disappeared in an amber flash. 

=======

Whoosh! Seems like our former archon has moon breathing, I wonder why...

Well, we are finally done with the Belobog arc and the next chapter would be the last chapter of the arc.

The reason why I did not have Cerberus go with the others is because he'd just kill Cocolia easily and it won't be a challenge for him to do so.

Omake:

"H-hey..." 

"What? Who are you?"

"I see, so it's already under effect, huh?" 

"Don't talk-"

"Kiana," 

"How did you." 

"You will never know me, but I want you to know... I have no regrets." 

"Quiet," 

"You always did cry a lot when you're alone." A soft pair of black diamonds gently gazed at the gem-like eyes of the goddess in front of him. 

"You're bleeding," 

"I have a surprise for you. It might seem cheap... but I can't let my big sister die. Heh! I still have that bet to win,"  Gently, the young stranger held his hand out and caressed the young woman's cheek. 

She did not know him, but why? Why was she crying for him!? And why did seeing him in pain hurt so much? 

"It's only natural to have the one to protect all things beautiful to see and cherish them," The cyan tips of his hair faded as his entire body faded into dust. 

"Rex..." Kiana whispered the name. The stranger was someone she just met yet... 

"Ah... I'm glad!" tears fell from the owner of the black diamonds as a beautiful smile was painted on his face. "Sorry... I can't... keep... our... se." 

Kiana Kaslana desperately clung onto the stranger as one by one, the memory that she had with him disappeared yet she called out his name. The stranger turned to ash, leaving a gate to be opened as a queen chess piece glowed from the ashes as the Hersscher of Finality was removed from the seal. 

Anemo's eyes snapped open as he held his head. 

"That memory again..." 

=====

Omake: 

Kiana Kaslana froze as for some reason, she felt that something she marked as her own was being threatened. 

"Bad Cerby! Stanky Cerby!" Reese shouted as she whacked the amber spear that hit her head a night ago into the ground. 

"It's concerning that Reese has managed to attune herself to the Geo element," Mei said, observing how the toddler managed to create a dollhouse and toys with said element and how she seemingly had a vendetta with the amber spear. 

"Well, knowing Rex... he'd probably get all depressed knowing that the techniques he spent a while to perfect took a toddler several seconds to learn," Kiana said with a smile as she watched how Reese made the statue of Cerberus once more before raising a brow when Reese kicked the statue's leg. 

"Auntie Kiana! Can I see a photo of Uncle Rex?" Reese said causing a small smile to appear on Kiana's face. Ever since she found out about Rex, she always tried to get as much information as she can out of them. 

"Here, Reese," Kiana said, gently taking out a photo that looked like it was a few years old. A photo of the two with Kiana in her Valkyrie ranger attire with Rex dressed in the male version of the ranger outfit. Kiana smile brightly as she hugged Rex from behind, peeking out of his bigger and taller frame while Rex was smiling a bit while rubbing her head. 

"Hey! That's Cerby, Auntie Kiana!" Reese said with a pout, causing both Mei and Kiana to look at her. 

"W-what?" 

"Silly, Auntie Kiana! That's Cerby!" Reese said with a smile as she crunched her face in focus as a bust of Cerberus appeared on top of her head, hitting her. 

Hesitantly, Mei reached for the bust of Reese's 'imaginary friend' and gasped. Those features were the same and it was unrecognizable from far away due to the new hairstyle and the amber but it was him! 

"I'm not talking to him for a month!" Reese said with a pout. "He called me a gremlin! And he stole Uncle Rex's face-thwack-" The amber spear she was whacking on the ground rebounded and the pommel hit her forehead knocking her out. 

"Kiana-idiotka, why is Reese knocked out?" Bronya said, before noticing a miniature amber statue of her and Seele with Cerberus in the amber playhouse.
