I'm so confused. I've had to go back after some History books but something's not working right. I've defeated Greystone twice but I never can get an X to "read" the book and my spellbook still says I need to get the book from the Plaza of Conquests. I'm also supposed to do the "Art of War" quest but Halina's face never lights up on my maps. She's supposed to give me a letter, right? Honeybee gave me a hint but I'm still stuck. Should I be talking to Tech Service?
