When I died I didn't expect to wake up with dark beings of immeasurable power looming over me. I didn't expect to be given new life in a brand new world. Now, armed with a powerful system that makes me stronger after every fight, I might be the last thing standing between the multiverse and absolute annihilation. As I complete quests, defeat foes and become stronger, I still don't know if I'll be able to save this world, my old world and all the worlds in between. "And below... the MAW beckoned..."

To be a King, one must set aside one's personal needs for the sake of others. But, when one was loved by the whole kingdom, the people prayed for his soul to find peace, and the gods heard of their wishes. They (the gods) granted the people's prayers and gave him the special gift of reincarnation. However, there was a catch... he will no longer remain in their world, but be reborn in another. The gods were happy with their decision. The young former king of Lucis, not so much. Watch as he sets on a new adventure in a world that is both similar yet so different than his own, while doing his utmost to remain as himself, (try to) avoid getting unwanted attention from unsavory individuals, and (attempt to) live his life the way he had always wanted to in his first life. (AN: Currently on hiatus due to real life situations. Updates for this story is set on 'pause' until the things in my life are properly settled and secured.) ... ... Author's note: MC came from FF15 universe, post-events, and transferred into an alternate world because of the astrals' intervention. MC is a responsible person. MC has a Neutral-Lawful-Good alignment (...most of the time). This story is mostly styled after the visual novels of the Fate series. The contents are detailed and lengthy. If you are into that type of novel, you are welcome to give this story a try. As for the update schedule for this story, it's almost always set on Wednesday. If I'm somehow busy on those days, then Thursday. Due to my responsibilities in real life, I can only update once a week. Two chapters of 2k words (1k each), sometimes more if I feel like it. Also, if you have some time, please leave a comment (or a review) of what you think about the story so far. Feedback is always important to a writer because it can help us improve our writing skills and create good stories for you readers to enjoy! :D Warning: MC is going to be OP. Character(s) death. Lengthy chapters. Profanities. The story mostly follows the plot of Fate/Extra, but will have elements from other animes as well. There will be some graphic content that might offend a number of people too. So, if you don't like that, or you are someone easily offended by violent content, please kindly refrain yourself from reading this story and find another that suits your taste. Thank you for your time! :)

Zhao Xu goes back 10 years in time to the day when Arthur's game servers opened. Only he knows that one year later, the earth will be destroyed and everyone on earth will transmigrate into the world of Arthur! PS: MC is a double character class of Wizard and Archivist, training in both the arcane and the divine, includes metamagic/magic guards/spells/rubies/action points/hyperactivity/pause/temporary effect/activation/in-game purchases in the making.

Magnus Webb undergoes a tragedy right as he enters the wizarding world. In his quest for revenge he becomes involved in a conspiracy that’s centuries in the making. As if all of this isn’t confusing enough, why is this Dark Lord guy always interfering with his plans? The story has a slow start and will pick up as it goes on. The 'system' elements aren't heavy here. The content will get mature as the story progresses. PS: I don't possess the rights to Harry Potter and English isn't my native language.
