It's really cool that Griffith cared enough to get things as accurate as she could, and not just stick in things because she thought it would be neat. (Okay, except that sparrow. Which I liked. :P :) )

Ah, grene and grenat... that does makes sense as a potential confusion.

So it occurs to me that the German for garnet is also granat (er, yes, it says something about me that this is one of the only German words I know), and some googling makes it look like it also came from the French. Which seems odd? I didn't think German had much French influence?
