Easy answer, Paladin. Said book was a relic: libram, those are only available to Paladins. Shamans use relic: totems. Combine with the warhammer, which a lot of Paladins also use in the Warcraft setting, in addition to wearing Plate armour. Game, set, match really. BE? Some type of magic-user. Could be Warlock, Priest or Mage. Think it was a Mage.
