The appearance of the Yith is really 2 for one, because we got the minds of the Yith, but the bodies technically belong to a sentient species that evolved on earth before humanity and that hijack by Yith minds. Makes me wonder if Polyps will be in the book as well.
Also I wonder if these bodies...
I wonder if Arcana Unleashed will have other references to the Forgotten Realms, we kno2 its companion book has some kind of Gazeteer on Thay and it has a FR wizard on its cover (actually it appears to have a small red wizard on the cover as well and a tressym as well).
Here is a dark possibility based on lore. Her original body got destroyed and her weave ghost did not have enough time to make a new one, so she she stole the body of a black woman, perhaps a wizard of Thay, and is now wearing her body as a skin suit.
Anyways I'm surprised no one is asking...
This the Arcane Empires Region mentioned in Heroes of Faerun, specifically Thay, set during a Wizards War. This one of the most high magic regions in Faerun filled high level monsters like Liches, summoned fiends (including a Demon Lord), and bordered on most sides by magic powerful nations...
I think if they took Cthulu while he's already napping it could make getting him alot easier.
My hope it mentions the fact that Cthulu is a priest of Azathoth, and we get options for building Clerics of Azathoth. & maybe appearances from other horrors from the extended Lovecraftian mytholose.
