This Umamusume: Pretty Derby lorebook—built from the game's content for AI chatbot characters—is my original creation by nokturn2008 (https://chub.ai/lorebooks/nokturn2008/umamusume-pretty-derby-lorebook-2b1b3a70c1c4). Unique structure, tags, tagline, and details, all mine.

MrDinoSD apparently thought forking it four times—unchanged, 1:1 copies—was a brilliant idea:

No permission sought, no response to contact, zero significant contributions—just lazy replication. Extensions or advanced versions? Fine, if original. This? Not so much. Decency suggests developing it properly, deleting the extras, or scrapping it all if it's just pointless copypasting. Forking isn't a free pass for thieves.

Lorebook created for characters from Umamusume. I've used Glossary (https://gamewith.net/uma-musume/69501), information found on the internet, and my own knowledge. The cover image was created by Malan (https://x.com/K0T0H1KA/status/1942540157456167048).
