The character you made

[Iscah]

The grimoire is called Ethica. It's a very pretty one, with butterflies and flowers. The type of drop you'd expect from a place like Dohn Mheg... except it drops from Castrum Abania?? It has never made sense that the pretty Fairy-looking book drops from a Garlean castle, while Dohn Mheg's weapons barely look fae at all.

Dohn Mheg's weapons are recolours of the Abania weapons. I think you're getting your dungeons crossed somewhere.
