Lark's Journal

Lark's journal. A leatherbound book filled to the brim with notes she takes whenever she's running errands, or at a local museum. She's always seeking new things to learn and add to her personal collection of knowledge. She got this journal at a bookstore simply to replace the one she had filled but, this journal was enchanted. 
Whenever the user writes in the journal, the ink disappears, and the journal absorbs the writing into the pages. Only the writer themself can summon the specific notes and scriptures written in this book. That way Lark can keep all her notes and writings in one place.
