Tbh the game is kind of like darksouls in that there's a lot of lore available, but it comes in pieces and fragments from items and other things so if you don't put in the work to piece it together it's very hard to get in idea of the lore. Plus with the time skip a lot of the lore isn't really relevant anyway, so just thinking of it as a basic fantasy world will probably be fine.

Edit: Should have someone from Bariura up today.
