I'm so hyped for this update. One particular thing that stuck out to me is the fact that they used the word "Purana".
Sumeru already has several references to Hinduism like Rukkh - devata ( meaning God of Trees in Sanskrit)
There are three types of scriptures in Hinduism
Vedas: The foundational scriptures that were directly revealed by the divine. (Considered to be the actual truth and wisdom)
Puranas: The allegorical stories that explain what is written in the vedas. (Legends and stories that serve as an allegory for the truth)
Smriti: it literally means memory. These account for the things that people remember from the vedas.
So basically In game, Scaramouche's actual life would be what happened while the allegorical story of Scarameow would be the Purana.
Does this mean that we'll finally know the actual happenings that are hidden in the stories like the Pale princess and the six pygmies? God I hope so.
