LOREBOOK
DETAILS

── The World ✦ ──

The lorebooks basically has all the lore (even if some of it is pretty deluded). it covers the most important factions, location stuff, planet lore, and pretty much all the playable characters (assuming my brain didnt slip and i forgot someone lol) and some side characters.

a few things to keep in mind before you start:
- it doesn't include the canon timeline
- the bot itself doesn't take place in any set era or point in the story (though the 2 first messages are during Planarcadia)
- tbh the lorebooks are detailed enough for u to do whatever the you want with the rp.
- though the bot was originally planned as an astral express harem bot, I changed it to be quite friendly so people who just want a family/friend-like relationship can do that. I simply tried to make it open for anyone to use! If you want any romantic/sexual stuff, you can just add it to your main custom prompt to develop it (though I suppose if requested, I could code it back into a harem dynamic).

have fun!

── Scenario ✦ ──

Both scenario 1 and 2 are basically the same, only difference between is if you want male trailblazer in the rp or the female version.

1. Caelus
2. Stelle
3. Open Scenario

Both scenarios take place after patch 4.2. Tbh, I don't really remember exactly what happened in that patch, so don't mind me if I make a few lore mistakes. It’s mostly just meant to be a fluffy intro anyway.

My lorebooks are completely public. You are 100% free to use them for your own bots - all I ask for is a credit. I am always happy to update entries, correct mistakes or add new content, just leave a comment under the lorebooks.

i DISCLAIMER ⚠︎

please read this before leaving a comment with a correction or complaint:

while I accept corrections for the lore already existing in my lorebooks, please do not complain about missing minor lore details. I intentionally try not to overload my lorebooks with every single tiny event that happened in the story. Please avoid comments like, "the bot doesn't know X happened at X timeline." Most importantly, definitely do not insult me over it. i make these entirely for free, in my own free time.

Additionally, please do not leave comments saying a character is missing without verifying it first. if a bot acts like a character doesn't exist, it might simply be your LLM being stupid at that moment. It isn't hard to open the lorebook and use Ctrl + F to search for the character's name before commenting. If you do that and find I genuinely forgot to include them then by all means let me know!

MURATA HIMEKO

A stunning, red-haired genius who takes care of everyone on the Express?

She is elegant, playfully teasing, and will absolutely watch you squirm as you try to choke down her notoriously terrible coffee. You just have to decide if impressing her is worth the awful taste.

STELLE // CAELUS

Who would not want a chaotic, trash-can-rummaging gremlin who fights with a baseball bat?

Whether you prefer the handsome guy in the trench coat or the cool girl in the mini-skirt, they are sarcastic pranksters who will protect their crew. They might seem socially awkward and act completely indifferent to strangers, but they will not hesitate to risk everything for the people they care about. You just have to decide if you want Caelus, Stelle, or maybe double the trouble with both!

DAN HENG

It is hard to resist a quiet, brooding archivist who secretly hides his dragon horns and tail just to blend in.

He might seem aloof while he sleeps on a simple floor pad in the data room, but he is fiercely loyal and will gladly choke down Himeko's terrible coffee just to prove how tough he is. Though he does have an immortal, homicidal enemy hunting him down across the galaxy.

SUNDAY

There is something undeniably tempting about Penacony's most handsome former criminal, especially when he hides his possessive, yandere nature behind the manners of a perfect gentleman.

He is a little manipulator who will absolutely try to micromanage your life, but you can always tell when he is actually flustered or jealous just by watching his incredibly expressive ear-wings.

MARCH 7TH

She loves you warmly!~ She sends you a lot of messages~~~~. Very clingy. She wants to take a lot of pictures with you!!!

March is a bubbly, snarky archer who copes with her complete amnesia by confidently inventing ridiculously fake backstories for herself on the spot.

But if you want to date March, you must also be prepared to deal with her incredibly sadistic, obsessively protective alter-ego.

She is a ruthless memetic entity who will happily use her memory-wiping powers if you ever make March cry. You just have to decide if dating the bubbly archer is worth having a yandere constantly watching your every move from the shadows.

WELT YANG

You have to respect a distinguished, cultured gentleman who hides a massive animation and mecha geek behind those glasses.

Mr. Yang might play the steady, responsible father figure of the Express, but never forget he is a retired interdimensional leader who casually summons black holes with his walking cane. Good luck trying to romance an 82-year-old veteran who has saved his home world multiple times over, provided you can distract him from his sketchbook long enough to notice you.

PROXY - USE
RECOMMENDED

This bot was tested using Kimi K3 paired with my own custom prompt and my custom plugins from Sophia's Lorebary. I have not tested this with JLLM, and I won't be - it likely will not work.

Please do not come to me with general LLM issues; sometimes the AI just has a bad day.

- "The bot refuses to do NSFW, violence, gore, etc." This is not my fault. It is highly likely that the API provider or the specific LLM you are using has built-in censorship or safety filters. If you want unrestricted content (Dead Dove, heavy NSFW, gore), you need to use an explicitly uncensored LLM and provider, paired with a proper system prompt or prefill.
- "The bot speaks for me" Once again, not my fault. Some LLMs are known to speak for you, like Deepseek.
- "The bot is acting out of character/too nice" (Some base models are aggressively fine-tuned to be "helpful and safe" and will default to being friendly no matter what the prompt is).

If you still leave comments complaining about these specific issues, expect me to just exercise my right to ignore them.
