The room of which Osira and Ada discovered, is perfectly sized as 10 meters wide and long! Whatever the reason why the Snow Ignites felt like they need a place this big for experiments or whatever else they did here, it seems unnatural.
It feels like a piece of this room is missing, as if someone dashed in and stole its contents. There isn't any food here, so Demons couldn't be the case. Or this could just be a theory of which Ada thought of.
As the left side caught their attention, they saw books. Lots of books, but not enough to fill the shelves! Yes, they discovered that there is more than one book shelve here. Three occupy 4 meters of the left side with ease, it reaches almost near the area where the room splits this mini library and the experimental side.
