The Alexandria library

What if the Alexandrian library didn't burn as people tought? What if it's secretly still here, but in a parallel universe, watched by its keeper and their assistants? What if Magic is still in this world but only some human can control it?
If this is the world you would like to live in, then this is the story for you.
Kinda based on my favorite series: The Librarians (hightly recommended btw)
