Over 40 pages of new material has been added to the Beta version (released May 2012) including:
Chapter III: Religion
Chapter VIII: The Laurëlorn Forest
Chapter IX: new Hinterglade (The Doomed Kindred) and Hinterglade design guidelines

...plus extra information on Brúidd spirits and Lornalim trees, a new Heirloom, and more. Playtest feedback has also been incorporated into the rules.
