Jan Bekker was a mage and likely the very first human to master the magic of the Old races. He subjected the "Force" to his will, thus granting humans powerful weapon in their many fights to come. He was a member of the Novigradian Union, along with Geoffrey Monck and Giambattista, and an original member of the Brotherhood of Sorcerers.
