Description
The book can be obtained from Gordon Ecker [Tyrian Loremaster] in Lion's Arch ([Prophecies]), Anja [Luxon Bard] or Gorani [Kurzick Poet] in Kaineng Center ([Factions]), or [Sunspear Signalman] in the Sunspear Greathall or Source of Whispers [Lightbringer Scrivener] in the Chantry of Secrets ([Nightfall]). It can be redeemed by the same NPCs for rewards if you have at least half of its pages filled. There is only a Hard Mode version of the guide. You carry it around in your inventory and fill it in by completing the specific missions from the three campaigns.
