Day 10 is the last book, but aren't we supposed to put together all the clues and go find something or open somehing with all of those words of power? Seems silly that EA just wanted to give players the ability to get free items just for clicking things and recalling places...
I know on Pacific, the Reds had a field day getting free loot from people who were doing the quest chain one book after another by camping at Books Nine and Ten. Sometimes people had cloaks and Talismans in their packs... DOH!
