I read a very interesting article that a fandom user posted and left me with one question WHY IS NO ONE TALKING ABOUT THE GROULS. The grouls appear in book 4 and we only see them appear a lot during the end of the book and then never again why?! Of course there could be a logical explanation for this as in the creator didn't think it was nessacary to bring them up again. But what happened to the grouls are they dead, are they still living in the catacombs, or where they a illusion brought to life by max. I also have another interesting theory they were elves. I know I will get a lot of angry comments about this theory, but what if they grouls are just the reanimated courpses of all the elves that died in the war example: Layra and her parents. Max clearly has the ability to make illousions but what if the guardian council used their abilitys to reform the courpses of the dead like how the grouls look and then bring them back to life. It would've been kinda easy for the best stonekeepers in Adelia. here's my theory after the ship caring Layra and her parents blew up they had people get their courpses and bring them to the guardian council which then use their magic to like make them looks like ugly grouls and then put them to guard their treasure it kinda makes sence because the elves are their swarn enemys and they don't want their enemys to like rest in peace it's the crulest punishment for a dead elf.
