After going into the room that Eshwar and Isha stayed in, Luna, aka Frostine, began to explain herself while Eshwar stood dazed, as if something in him was on the verge of snapping.
After she died, saving Isha, she experienced something she never thought would be possible, and that was "rebirth." Who knows why and what it happened for, but whatever the reason was, Frostine found herself in the world of dragons.
While she struggled for her survival, by the time she noticed it, she had become an elemental ruler, the ruler of Frost. It was an age of war in the dragon world, in which the elemental rulers themselves participated. Though none really noticed it, Frostine could tell that the world was falling apart; there were cracks forming in space whenever the rulers clashed; and a few years later, the dragon world was filled with cracks as the war was about to finally come to an end, but whoever, for whatever reason, pushed Frostine into a humongous crack in space.
Her vision blurred, and enraged by the fact that she was betrayed, she used her strongest breath before passing out. Later, when she opened her eyes, she found herself in an unfamiliar world that had an extremely weak amount of mana, and the oddest thing she noticed was that everything around her was covered in white snow, which was the effect of her breath, which would turn any living being into crystals upon contact, without exception.
She made herself a lair in the coldest mountain that existed near her, before a human-like being approached her lair and challenged her to a fight. Due to her boredom and loneliness, she played along with him, but before she knew it, it had become a routine, and that human-like being had become her friend. They both shared their stories, and she learned many interesting things about the world called Earth and about the mountain she made her lair in, which was a great mountain that had a moniker attached to it as "Mount Everest."
While enjoying her time with Eshwar, she learned about regressions and rebirths, which were described quite well even though it was just his theories, and later that "regression" kept happening to him and he had turned almost extremely emotional yet emotionless.
And in that life, the last thing she remembered was dying to the intruders that intruded "their" lair while protecting Eshwar out of pure instinct. Even though she knew him for that long, she never felt her heart grow fonder of him, nor did she develop any affectionate feelings for him, because for whatever reason she knew in the back of her head that her feelings wouldn't be reciprocated.
After her death, she opened her eyes again and found herself in a small, bruised child's body that was tossed next to the dumpster in the slums. Since it wasn't her first time, she wasn't that surprised, but after learning that a few nobles had killed that child for stealing a handkerchief that looked pretty, she got enraged at them and killed them before running away, taking everything that seemed valuable.
She explored the human world for a few months and learned that she was back in the world where she and her master, Isha, once lived, on the planet Antinoüs. But it was extremely different from what it was when she was still alive in that world, so she continued to explore that world anew, because she had never really seen the outside world when she was serving Isha, while creating a dragon's heart using the purest mana available.
The creation of a dragon's heart from scratch was possible, but the knowledge about it was only passed on to the elemental rulers, which she was, so she didn't have that much of a problem creating one. Later, when she was in search of Isha, she came across the pocket system, which had influenced the entire planet. Using it to the best of her abilities, she got stronger so that she would be able to protect Isha when she found her, unlike her past self.
She searched for Isha for years but found her nowhere. Remembering how the nobles lusted after Isha, she began to hunt down the nobles and royals, nipping at the edges as she made her way in. But while she was in that process, she came across a group that was doing the same thing as her, but far more efficiently and effectively. Proving herself, she somehow managed to join the group, but it was still far from enough to finally be able to meet the group's boss.
Years later, she finally learned that except for those nine people she saw from the beginning, no others really existed in the group, and she was stunned beyond belief when she learned that the boss of the group called Veil was none other than Eshwar. She then learned about his lover, whose name was Isha, her master, and finally about Eshwar's promise to return. It was from then on that she began to notice similarities between the pocket system and the one from the latter part of the story that continued in his novel.
The group waited for Eshwar as they maintained the group and kept the royals in check, and amid everything, her desire to help Eshwar in whatever way possible grew. And she thought of making a connection with the planet Earth. Due to her persistence, she began to cause mana explosions, which were the reason for the cracks that appeared in the dragon world, wasting her mana.
After years of persistent efforts and mana explosions, she somehow managed to become the "head admin" of the system that influenced the entire planet Antinoüs, gaining herself a glitched system interface. She used that authority she gained and exploited all of its uses, finally making contact and establishing a connection with Earth. A crack opened up in front of her, and when she walked into it, she walked into a world where mana didn't even exist.
It was just like what Eshwar had always described in his stories: she was happy, thinking that she finally had the opportunity to meet him again, but she was unexpectedly caught by a human woman, who was wary at first but soon claimed herself as Frostine's friend while calling her Ms. Alien.
Not minding the weird nickname, Frostine asked her about Eshwar, whom the woman fortunately knew as an author that died; after learning what she came for, she erased the woman's memories after learning about her name, Seol So-Young, and left the planet before too much mana influenced the Earth.
After returning back, she began to search for the Earth that contained mana; because she was used to searching for one, it wasn't that hard to find another, and she found it not so long after. With more massive mana explosions that were influenced by the glitched system, she formed a connection with the other Earth, where she was sure Eshwar was, and the connection was formed through gates.
But the gates were one sided, in which one could enter but they weren't able to leave. Even though she knew nothing about what was happening on the other side, with him, since she had the head admin authority, she understood that if she abused it, the system would react to it accordingly, and the possibility of Eshwar coming to their world to fix that problem would be high, which was the reason she abused it by making monsters and beasts of her current world enter the gates. Due to the mana limitation of Earth, she wasn't able to send stronger monsters right away, but just like the level-up function, the mana limitation slowly expanded until she was able to make a minor god enter the gate.

(AN: OMNISCIENT POV)
After a few minutes.
"So, you did all that to make us enter this world faster?" Eshwar, my other half, asked, dazed, while Isha continued to stare at Frostine without a change in her indifferent expression.
"Yes." Luna, aka Frostine, said with a bright smile on her face.
"Let me ask you one last question. Why did you save me even when you knew how strong I was?" My other half asked in a daze.
"Ah, t-that was out of pure instinct that I had developed when I was with my master, Isha. I always had the thought that you were a lot like her, so my body would move by itself before I even knew it." Frostine spoke with an embarrassed expression on her face.
'What's there to be embarrassed about?' I thought.
"You mean I'm a lot like her?" He pointed at Isha.
"Huh? What do you mean? I'm talking about my master Isha, who died, not a woman who has the same name." Frostine said with a frown.
'She is still as dumb as ever.' I thought.
"You know me?" My other half asked.
"Hm? Of course!" She replied without hesitation.
"And you know I loved Isha, your master?" He asked in a daze.
"Yes!"
"You know how I am. You also know that I loved Isha. Then why do you think that I loved another woman who has the same name instead of Isha herself?" He asked, making a valid point from my perspective.
"How would I know? I don't know where this topic is going, but if I'm right, then you only love one person...huh?" Frostine said and frowned in confusion.
"Hi....Frosty." Isha called out, and by the next instance, tears welled up in her eyes.
"N-no, no, she is dead; sh-she is supposed to be.... d-dead." Frostine mumbled while tears streamed out of her eyes.
"I missed you...can I get a hug?" Isha asked, extending her arms.
"Isha!" Frostine called out and jumped into her arms like a little kid.
THUMP!
"!!!!" The eyes of those present widened when they saw my other half's body slump down.
WHOOOOMMM-!
Then,
"Hing~" I took over, standing back up and cracking my neck and other joints before turning to face Frostine with cold eyes and a sweet smile on my face.
"Devour her authority." I commanded the system in a mumble, ordering it to take away Frostine's head admin authority, and
[Initiating...]
[Initiated task completed.] As soon as that message popped up, I knew that Frostine felt something disappear from her.
"Copy her memories." I commanded again, but this time, I made it so that my mumble wouldn't be heard, nor could it be heard even if they tried.
[Initiating...]
[Initiated task completed.]
A few seconds later, "I missed you too." I said, gazing at Frostine and Isha, before my gaze flitted on the others, unmoving.
"Boss-!" The group of nine called out in unison.
"Hahaha, I missed you guys too." I said it with a small chuckle, but there was no change in my expression.
FHUMP
"!!!!" Finally, my expressionless expression crumble down, into pieces as tears streamed out of my right eye.
"Ah...." With a strange sound, I glanced down and saw Isha hugging me tightly.
With my brows and lips trembling, my arms moved, and everybody present saw my body trembling, and the hesitation in me as I thought whether to return Isha's hug or not was extremely clear; they didn't know why for what reason I was acting that way, but they felt their hearts clench painfully.
"You...are not going to hug me?" Isha asked, looking at me with a smile on her tear-filled face.
'He is not the one from before...' The group thought in unison.
"C-can I?" I asked back with a pained expression on my face; actually, I was scared to even hear an answer from her.
"Why are you asking permission? Aren't I yours?" Isha asked.
"I, I don't know. You won't become mine if I'm the only one who thought that, and I definitely said that you are the only person I ask permission from." I replied and waited for her to answer.
"Please hug me." Isha said as her smile, too, trembled. Tears began to stream out of my eyes, and I could feel what the others around me were feeling, which was annoying since it was distracting me, so I controlled my omniscience.
And,
"Can I hug you.... please?" I asked, and noticing Isha nod her head, I hugged her. I HUGGED HER. A sense of relief and satisfaction washed over me; if I had to describe it in different words, then you could easily and honestly say that I felt like my soul was finally at peace. I took over my other half's body for a different reason, but... well, not that I would ever complain if it included Isha.
