The Legend Of Bob

So, i found a fireplace in ragni castle with: "In memory of Bob" written on it.
I threw in bobs tear and the fire went away as well as a message came up with something in the style of this (not 100% sure): Those who seek knowledge should enter my castle. You then enter the castle in the painting at the dinner table, and it takes you to a long hallway with 12 chapters in it. These are the chapters.

Now, im not sure if this is just heavy lore, or related to ???. If you think this is related to ???, just make a post there linking this thread.

Please tell me what you think this means below. Im guessing other people have already seen this, but i decided to post it.

 

it isn't related to ??? this is old lore

 

i know its old lore but the room wasn't there before
