Ya know, I'm really glad you didn't mind the inquiry. I'm one of those types who likes poking around, as you can tell, so I'm really happy that you don't mind people doing just that (as long as they don't spoil everything, anyway).
On the topic of spoilers, though — and specifically flags…
[Secrets spoiler (?) spacer]

I noticed two "unlockable" flags that seems persistent, and they're the ones I was actually curious about when I brought the topic up:
- "green" (written at game start) - When set to 1, Bellagarth is hued dark green for most of her animations. (Not shared animations, like being grabbed by the Chelnok watchmen.) Also lowers the speed of her voice by 49% (except her "guard broken" squeal).
- "fart" (written after 1-1) - When set to 1, Bellagarth occasionally farts when jumping.
I don't recall these flags being relevant anywhere, and they seem to stay set once written into the save, so it feels like they were Easter Eggs.
As for the "growl" flag? That was my mistake. I thought having that enabled modulated Bellagarth's voice.
Once again, thanks for all the answers! Looking forward to the next book!
