Hero's Handbook

The Hero's Handbook is an item you carry around in your inventory. Completing primary quests will add an entry to the Handbook. Upon completion of all 16 Primary Quests you may turn it in to Tyr the Skaald (Norn), Kodan (Deldrimor), Lexx (Asura), or Gedrel of Ascalon (Ebon Vanguard). You will recieve 2,500 points towards the title track of the race your turn the book into. You may then start a new book and redo all primary quests again.
 * Note, completing primary quests without the Handbook in your inventory (e.g. during the sneak peek weekend) will not add them to the Handbook.

Trivia
While a little bit of a stretch compared to the Master Dungeon Guide, the Hero's Handbook may possibly be a reference to the Player's Handbook of Dungeons & Dragons fame, from which Eye of the North has apparently borrowed somewhat. As well as having a similar name, the primary colour of the book icon is close to that of the real book.
