WOW!
The Library of Eridel sounds super cool and eccentric! It'd be a complete dream come true to have a library the size of Paris.
I was given this impression while reading over your description of the wonderful place:
It sounds kind of spooky, and I imagined that some of the books would be shiny and new, while others would have yellowed, tattered pages and dusty covers with worn out titles. I imagine a distant humming type thing, just making the whole place eerie but impossible to leave, especially for those who are hungry for knowledge. Like every turn you take, you find a new universe to explore, and you just can't make yourself leave because there is so much to see, so much to learn. I imagine people getting lost in the hallways but not even caring, not wanting to leave, because there are just so many possibilities and amazing things to discover. Maybe even staying there for years, losing track of time, just reading and cramming their brains… losing sanity, possibly?
That's the feel I got from it. Maybe that's not what you were going for, but I'm telling you, it sounds really good!
