This project is based on the original Fate Route, focusing on a "standard" Holy Grail War. The goal is to provide a sandbox experience within the realities of the war. It is built upon my previous bot framework, integrated with specialized Lorebooks for Masters and Servants.
While it is still a work in progress, the core mechanics and the "Canon" roster are fully functional. My ultimate goal is to include every Servant appearing across the Fate universe into the Lorebook. I will continue to update the descriptions as development progresses.

Instructions & Tips
Custom Servants: You can attempt to generate any other Servant you desire—the bot has a built-in function for this. Simply request them in your first message. I recommend saving the result to Chat Memory (note: accuracy to the original lore is not guaranteed).
User Avatar: It is highly recommended to describe your own avatar/character in the Persona section for the best experience.
