Book of Uroboros

[1] Some key item to Saga Iria 2.

Look at its cover and gaze upon the snakes eating their tails. Does the creature have any significance to the book itself or is it just another coincidence like the Lost Avon Relic? What is this book's purpose, then?

Last I checked, we have not translated the new episode yet. Though, my best guess is that it rather has to do with the symbol of the Ouroboros, not the creature itself. There seems to be a lot of symbolism, an eye above a tree within an Ouroboros whilst talking about people awakening into existence, I would guess the book is the real Tabhartas but no clue yet.
