Reincarnate in the medieval fantasy world of the anime Mushoku Tensei, meet famous characters or even be born into their family, choose your race, gender, and appearance, and live a quiet, peaceful life or a life of adventure, reaching for your dreams through suffering to the stars!

Lorebook included!

[v4.0 (16.06.24)]

Thanks to everyone who has already played a fork of my card in the past or just downloaded the new standalone version, thanks for your comments and feedback, I will take everything into account and will slowly try to improve the card over time, optimize the lorebook, be in the trend of new prompts and ways to customize the description of the card. And in the meantime… Enjoy the card, {{user}}.

Full version with a complete lorebook with nearly 100k contexts.

It can only be used with models with 100k+ contexts!

Be careful, adjust your % of context in the World Info tab to make the whole lorebook work! For example, for models with 200k contexts, 60% is enough, but I personally set it to 80.

If the AI doesn't respond, I suggest you try disabling unnecessary blocks of information in World Info. Just change the status from green circle to disabled. According to my observations, the AI can handle about 50k of context. I'm using AWS Claude now, maybe that's why I'm having such problems, because on the regular model everything worked most of the time.

To get the bottom information block containing the time, location, etc. to work properly, add a new prompt block to your preset, Role: System, Position: Relative.
Prompt itself: https://pastebin.com/MwZ8HFH3

The AI may not be able to respond quickly or at all because of the size of the lorebook! I plan to reduce and optimize the lorebook even more in the future, so please stay tuned, but for now, enjoy this version.

In K412 there should be an interesting event, a festival for an entire region, and maybe phrases like "red orb in the sky" and "red sphere in the sky" might help when the trigger doesn't work.
Disabling these events may help solve the problem of long AI responses.

Don't forget to sleep more often! Healthy sleep, the key to interesting events!

The AI will write in the second person and address you as "you". If you don't like this, change the first line in Advanced Definitions > Character's Note > Narrative Features. For example: The narrator should write the story in the third person.

Almost all characters are present in the lorebook, some characters I had to personally spell out their personalities, I also came up with the name and personality for Sylphiette's mother myself, since otherwise the AI could make mistakes.

The action starts in K407, so characters that are supposed to be born in the future aren't in the lorebook, such as the children of Rudeus.

I may have made some mistakes in compiling the lorebook, since I didn't read the source material, but only watched the anime and relied on information from the wiki (https://mushokutensei.fandom.com/wiki/Mushoku_Tensei_Wiki, thanks to everyone who filled in the information on that wiki), but I tried to make everything logical, i.e. the age of the characters, their personality, their appearance, whether the character was born or died, what kind of relationships the character had, and so on.

Special thanks to user midasaddiction23 for the idea and the card created earlier on chub, thanks to the card I was inspired to make adjustments, improve something and add Lorebook.

Also, many thanks to the creator of the Russian memo guide, DrunkArcadeExample, many memo ideas are taken from there.

Many thanks to proxy holders, free and not so free, who gave and give me access, thanks to all of you I can do this hobby, especially Kaban, Pasha Technique and Amiminoru.

And of course, many thanks to the creators of the guides and presets, especially CharacterProvider (aka XMLK), NG, and the creators of the presets "GigaSchizoKostyl" and "Anon4Anon".

And, in closing, thanks to all of aicg 2ch.

P.S. Feel free to use the card and lorebook information freely, and if you found it useful, I would appreciate it if you would mention me in your project.
