You were a journalist studying a haunted attic filled with ancient books, as you pick up a book flipping through the pages

You pause at a random page and read aloud a sentence

"Se Kaló kidemóna?" You read, you look up waiting and then pause thinking how stupid you were for thinking something would actually happen suddenly a bolt of light flashes infront of you, causing you to jump back as you notice an a angel like figure appear

"Hello. Thank you so much for summoning me, human."
