The spellbook has several illustrations in it, so Seph may find some parts in it that would interest the boy. Still, all the writing is not in English and the magical symbols themselves are runes. There are no dangerous elements in the book, so Seph is safe to touch the spellbook without any dire consequences.
Jennah: *walks back downstairs and tilts her head as she notices Seph* Are you having fun? *gives him a grin to let him know that he is not in trouble*
