I'm glad you're interested! We're very excited about this book.
Dark Inheritance will be in stores this April, so keep your eye peeled and ask your retailer to order you a copy.
As Wil said, this is an "excellent and specific setting." We wanted to grab from the action movies we love, like Replacement Killers and Pitch Black but incorporate mystacism and magic that while compatable with d20 was fitting for a modern campaign. And I can say it is even better than I hoped.
As for previews of Dark Inheritance, you can expect more soon. In a few weeks we will begin to reveal the five Titan legacies, the lineages of gods and monsters.
In March keep your eye out for Campaign Magazine. Inside will be a full preview of Dark Inheritance and you'll get a sneak peak at Sam Witt's Relic rules as well as an exclusive that will only appear in Campaign Magazine.
