Since the previous release, one clan is the main focus during each update, allowing to further develop the relationships and the drama of that clan to provide a more complete play-through. 

This v0.6 update has the DR tag as it mainly contains Dark Raven's content in order to further develop their storyline. Therefore it means that you will need to start from a save on the DR path. Beside the Raven's girls, you'll also enjoy a nice storyline with Astrid and Yrsa.

And you can expect that the following update (v0.7) will feature White Wolves.
