So read a bunch of books within this infinite library, perhaps find some heroes who you like and bring them beyond their book and into your realm, give them a bit of your power to put them above all who exists within the marble... making a guild... or something like family, of heroes. I mean I'm pretty sure you've all dream't of interacting with character's of stories which you enjoyed, to assist or whatnot, but perhaps the thought of "its just a story" "its just fantasy" messes with your mind.
