Ruby of Enlightenment

In the first 4 books (Lore of Arcana), we hear about three devices/artefacts that drive the story. So far I've shown you via AI art prompts how I envision the Ancient Oracles and the Maghdim Medaillon.

Yes, there are other sacred tools, and we'll get to those, but these three are most important initially. To that end, there's one missing and that's the Ruby:

Had a hard time trying to explain to AI what I'm after here (a 14 facet gem large enough that it needs two hands to hold) and this is the closest. It's larger than this in the books, but oh well 😅 

Everyone advocates for the destruction of these devices, claiming contained magic is dangerous - which will survive into the endgame?
