From the White Wolf Website:
Sometimes writers write too much.
The Compass of Terrestrial Directions, Vol. II-The Wyld offers many locations, people and creatures for Exalted games, but the writers produced quite a bit more than we expected. It seemed a shame just to throw the excess material away, though. Then, over time, other books ended up with little scraps and fragments of Wyld lore, and those seemed too cool to leave in the oblivion of a computer trash bin. Before we knew it, we had a lot of pieces with no home, so we decided to stitch them together into a crazy quilt of additional game pieces for your Exalted series.
The result is Splinters of the Wyld, additional glimpses of the madness waiting at Creation’s rim. - A PDF-Exclusive Series Book for Exalted
Splinters of the Wyld contains:
New locations for the Northern, Western, Southern and Eastern Wyld
More Mutations and Deragements
More creatures and characters
