SCH pet glamors?

[Rawrz]

The fairy exists in some capacity regardless of the player character. The quest journal makes it pretty clear, the fairy slept for 1500 years within the stone, she seems to be the exact same entity as she was over millennia ago and even remembers her previous owner. In comparison the Summoner stone provides no such inate summoning capability, you have to go and summon tiny primals and enslave them to your will.
Considering it displays much more independent thought and action than any other summon forcing it to inhabit the body of a carbuncle, if it's even possible, seems almost cruel. The game stubbornly refuses to give us the option to be bad guys .

Edit: Journal quotes.

You haven't actually proven anything against her claim, if anything you strengthened it. Lilly hibernated within the box with her soul stone. The moment Lilly dies (unsummoned) you construct out of aether, another vessel for her. Kinda like you uploading all your memories and personality to a cloud memory bank. You die in a knife fight because your cousin Rickey forgot to sharpen the blades. That damn Rickey. But it's alright, because the boys back at the lab have made you a new body and uploaded your last memories into it from that cloud storage. You died, but you're alive know, completely knowledgeable on events up to the point where you died! Are you immortal? Kinda. You'll keep learning that's for sure.
