From the introduction: This is a supplement to the Drakenfjord v4.0 Player's guide. It contains a variety of special rules and advice on how to get the most from the game. This is written for the player's benefit, although Reeves, Questmasters and Battlecrats should also be aware of this information and will find it useful.
