chapter 8 draft, minor detail changes, codex updates

So far…

• 109,961 words (based on illume proofing calculation)
• chapter 8 might still have continuity errors (because of the amount of flag variables to check), feel free to let me know if you catch any
• tweaking minor details here and there as I learn new things from research, such as the 12 patterns for the cloth of the king/emperor, Jian bird (instead of calling it “biyi”), etc.
• added more entries to the Concepts and Factions section; added a simple Timeline section
