Hmm, with everyone talking about how much they're affected by their Grimoire, I wonder if that gives Lilac an odd story with how much she worries about not being effected enough by her Grimoire.

Mayhaps...
We've got some interesting options abound, and the degree of mental pollution varies quite spectacularly. From what I can see:

Lumiere: Sinisterly subtle influence. A slow but steady change over the past century that has induced a calculating self-righteousness.

Camelot: Similarly subtle in its own way, but a bit more ham-fisted in others, often tossing foreign instincts and dialogue into her face. Does not really directly influence her personality and more expands her knowledge, which ends up influencing her decisions by proxy.

Dynasty Queen: Seems almost hilariously bold in its influence, but it's sinisterly difficult to tell because her base personality is so compatible with her Grimoire.

Lilac Shimmer: No discernable changes. Ironically, this bothers her. Love it.

Captain Goodhope: Unknown. Seems to be just a completely genuine take-her-at-face-value person.

Burning Heart: Fills her with courage, boldness & fearlessness. (Lonewolf WOG: she is entirely controlled by her Grimoire when transformed)

Ethereal Rose: Becomes more serene and refined (yes, because what we've seen so far is apparently the poor thing [i]holding back[/i]). Be afraid.

Lady of the Lake: Mostly appears to be combat instincts... [i]for now[/i].

Ozma: Unknown.

Roma Bahkti: Unknown.

Grand Minister: Unknown. She's been around a while though, and something as powerful as the Merlin Grimoire is unlikely to come with [i]no[/i] baggage. (included for TheWendil's peace of mind XD )
