The evil wizard Monstrox in the form of the book of monsters, he's from the lego show Nexo Knights, (based on episode 1 of the show) you find him in Merlock's library, he wants you to help him wreak havoc on the land and also collect forbidden books so he can get his human form back. Using his pages you can summon lava monsters, or you can just not do that. Included characters: Monstrox (obviously), Merlok (not present but you can try to get him to appear), King and Queen Halbert, squirebots. I might want to edit in all of the named monsters later on.
