It seems that virtue gems come from the moon, lots of hints inside

Maji could be any number of other things. Hell, it could be the beast. Or some deity the Vaal worshiped.

The Divination Card supporters write their own flavour text, so I wouldn't read too deeply into the lore that they imply.
So the cards text are not reliable.

I know I’m necroing a dead post but reading your post made me realize this lore is probably path of exile 2 secret quest lore as well.

What’s intriguing about your post is mana sponge moonstone ring. To my knowledge it is an unfound item in Poe 1.

Right away in your post it says “I would have given you the moon but it couldn’t be found” probably an elude to the fact he wanted to give her the mana sponge moonstone ring.

The artwork also eludes to a stone version of the moon in someone’s hands. And when you turn in the card for the staff it says “what is broken can break further” a probable indication you have taken a bad action route of the quest and to repair it means starting over.

After about an hour of thought into it I concluded that the name “Mana sponge Moonstone ring” is an anagram and the only actual hint.

The best I can do after 15 minutes of anagram work is “gone maps an one moon string” I however didn’t play poe1 and don’t know anything about the lore.

Though I will add that the tail. End of the art does look like a map of different areas separated.
