My Succubus Harem System

Mrs. Margareth nodded, "That dreamy old man did a lot in life, maybe this notebook will help you. I'm too old to read archaic Elvish, so if you can decipher it, tell me a bit about what's written in it."

As Ryan flipped through the pages, it became clear that it wasn't archaic Elvish. In fact, the language used was much more like the common demon language of the second world. In parts, the two were relatively similar, but it made sense that not even the author's wife could understand what was written.

"I... I can read," he said, causing Margareth to take a step back. When Ryan raised his head, he saw that lady crying. Tears streamed down both sides of her face, as she covered her face with both hands, "I never thought this day would come," she said.

"Thank you so much for this gift... I promise I'll pass on Eliot's messages and ideas to you," Ryan said.

The lady then opened her arms and threw herself on Ryan's chest, "I don't know how to explain it, but this duality of energies, Eliot was exactly like you," she said.

Ryan was surprised, 'Someone like me?

"My son, please take care of this book and study everything you can. If you can, please tell me what he was writing before he died," she said before leaving the room alone.

In front of Ryan was a question and an answer. Eliot Wright was one of the great names in the study of magic, having created the classification of blue, red and green portals, as well as being an important part of the Last Impact fight. He was one of the guild's great heroes, and had stories that gave even the guild's most skilled Rank SSS+ travelers goosebumps.

"If you are reading this book, firstly you are an inhabitant of the first world, secondly you are an inhabitant of the first world who has understood the demonic essence. I could write this book in the language of light, but it's not as widespread as the standard demonic language that can easily be found hidden between books. Besides, it's a bit amusing to imagine dozens of people racking their brains thinking I'm writing in some special archaic language, in some weird dialect from an isolated forest of pointy-eared people. 

It took me about four years to be able to read this dialect, so I won't stress you enough with words that I don't even know the true meaning of. This is my diary, here are notes about my explorations, I ask you to be careful with the information." This was the opening of the first page.

The message that was written on the next page was something that Ryan had already imagined had happened, but which still left him more frightened than he should have been. 

His body froze as his eyes glazed over at what was written at the top of the page, a text that could finally answer the doubts he had been having for so long.

"Chapter 01 - How to create a portal to the second world"

***

Portals are dimensional rifts, something that has already become a kind of common sense. It's a connection through mana that breaks through reality, joining two different places. At first glance, this may be a complex concept, but the truth is the opposite.

Imagine our world as a sheet of paper, a portal is nothing more than a small origami of mana that unites two points. Now, what is a portal to the second world? What would an impact be? They are the result of friction between two sheets of paper that remain touching for a long time.

--------------------------------------- There was a line written in the middle of the page that led to an annotation in the corner of the sheet.

Ignore this theory, portals between dimensions are the result of the wishes of the Gods of the higher plane. Although there are sporadic portals that appear without apparent explanation.

The connection between the two worlds is made through a flow in time, a point in the past where a region is captured by this interweaving of realities. 

Last year I managed to open a portal, but when I asked my girlfriend to do the same, the spell was destabilized and only created a mana barrier. 

-------------------- To create a portal to the second world, you need to have a direct connection to it. Either through exposure to an energy source. I was exposed to a Jhinn in a dungeon, so I imagine there are other possibilities.

Once the connection is established, anyone can cross both ways. Although time acts in a funny way in the second world. When two portals are connected, the flow of time will remain constant, but when there are no portals connected to the second world, time simply freezes. 

One way to test whether there are other portals connected is to activate two timers, one inside the second world and one on your wrist. Once you leave, the stopwatch will stop while the one on your hand will continue. -> If there is any doubt about the possibility of other portals, carry out this test.

"So I can do this..." Ryan said out loud in surprise. Before he could get up from his chair, he was surprised by Margareth's voice.

The sound of a cup being placed on the table echoed around the room, "Here, some tea. Have some before you leave," she said, her eyes still a little red, as was her nose. It was a little sad to imagine how much that old lady missed her husband, and seeing these effects made Ryan feel a tightness in his chest.

For a moment, his own head reminded him that he should now be dead. The very permanence of his existence on this earth depended solely and exclusively on a blessing, a cheat he had acquired.

"Thanks for the tea," he said as he held out his hand. The warmth of the mug passed through to his fingers as he brought it close to his mouth, and the smell of the steam rising to his nose brought him a huge sense of relief. "Hibiscus tea with apple and honey, that's a different choice," he concluded, as he took his first sip.

Old Margareth Wright started laughing at Ryan's words, "It really is a different choice, that was my Eliot's favorite tea. He used to leave a five-liter bottle next to his desk when he was working, even this notebook has some red marks from the hibiscus tea that idiot knocked over Hahaha."

Ryan and Margareth continued talking for a few minutes, the woman seemed to be trying her best to ignore the pain and anguish she was feeling. After a while, the subject turned to Eliot's requests.

"Once he called me in the middle of the night asking for help with solving a magic circle, the sound of the call was weird. It turned out that he was inside a red portal fighting an ogre mob with the guild," she said, laughing.

Ryan was surprised "How did he manage to get in touch with you?" he asked.

Looking from side to side, that lady put her hand to her mouth as if she were telling a secret "He made a portal on the outside and linked it to the inside of the portal. Then, when the situation got complicated, he turned his head and phone to the outside and called me."

"I can only imagine what your reaction must have been!" He said.

The two of them started laughing about the situation, and now Ryan had a slightly better idea of what the author of that book was like. Eliot Wright was an amazing person, and it made sense that he had so many discoveries and achievements.

"The only thing I still regret is not understanding his studies. He would ask me strange things sometimes, to test spells or open strange portals... Then he would write them down in his book and never explain what was going on. To tell you the truth, I never really asked," Margareth's voice became a little despondent now, as the memories rushed back into her chest.

"What kind of things did he ask of you?" Ryan asked, puzzled. But after reading the book, he already knew the answer that would come.

"Eliot had a thesis on portals," she said, holding out her hand and beginning to channel a magic circle that was identical to the one Ryan used to open a rift to the second world. But as soon as the spell was completed, nothing happened, as if it simply wasn't ready to be real magic.

"He asked me several times to open that same spell, sometimes in different ways. But it never closed, maybe you can complete his work," she said.

Ryan's thoughts were now aligned. If Margareth doesn't have an energy that connects directly to the second world, then the guild still doesn't have access to the resources there. But that still didn't explain how the old Silvermoons did it.

As his thoughts flowed, more questions popped into Ryan's head.

 'Is it possible to go the other way?
