Merlin loved books, he loved learning. Knowledge is power after all. Besides, he needed to keep up on all the knew magic out there if he wanted to stay the most powerful sorcerer to ever live.
Okay, so he didn't really care about that, he doubted that he was anymore with all these new witches and warlocks showing up every second.
Anyway, he craved knowledge and a new bookstore was the best place to find it. With a clink of doorbell, he entered and started to browse a shelf of books.
