The library.

You begin to wander around the castle hallways, looking for something. Eventually, you find yourself within large shelves filled with rows upon rows of books. While at first you think this is a library of some kind, a nearby sign points out that this is, in fact, a "Librarby." There is also some scribbling on the sign, explaining that this place "is strickly for NERDS only; like RALSAY!" The sign further goes on to explain, in a much nicer handwriting, that "It's spelt 'strictly,' Susie. And please don't vandalize signs." The vandal then goes on to write, "Like I said, NEEEEERDS!" A third person's handwriting follows saying, "She's right you know." The nice handwriting expresses it's shock by writing, "KRIS!? Not you too." The back and forth banter goes on for some time, eventually running off the sign and down the wall to the floor. As much as you want to keep reading this to the end, you decide to press deeper into the maze of shelves and old tomes. After just a bit of walking around, you see Ralsei, who is staring at a series of glass murals high on the wall. Some of them feel very familiar to you. You hear Ralsei muttering to himself. "I don't get it, nothing has changed since the last time I read it. And yet, Vessel still showed up here. Could another dark fountain have opened up? No, otherwise they would have appeared there, and not here." Ralsei stares at the tablet intensely, without saying anything for a few seconds. "Hmm, I guess there's no answers here. I'll just head to bed then." It is then that Ralsei turns around. When he notices you standing there, watching him, he jumps a bit, before calming down. "O-oh, Vessel. What are you doing here?"
