There was lots to digest, but a few tidbits off the top of my head:

- Yotsuyu's full Garlean name was Yotsuyu goe Brutus (not sure if this was mentioned in material prior to the book coming out)
- The Fenrir we see in Snowcloak was basically just Ysayle's pet attack wolf she named after the legends, so technically there could be a primal version of Fenrir in the future
- The book acknowledges that the legends of Tsukuyomi in the context of Othard aren't terribly clear on gender, and that some interpretations did depict Tsukuyomi as a male. Don't have the book with me atm, but I believe the primal Tsukuyomi was female simply because the vessel for the summoning was a woman.
