Echoes of the Sundering - DT Preview with Mark Streed

About Echoes of the Sundering, from BoardGameGeek:

You have come to the Rooted Soul, the massive tree that stands on the border of the Anwyn Valley, in response to a crisis. For years a poisonous fog has filled the Valley. Soon it will expand and swallow up the rest of the land. Some of you have a nearby hamlet or village you call home. Some of you have heard that there are great and ancient secrets hidden in the Valley. Some of you long for a chance to prove your prowess. But all of you agree that the fog must be stopped before it poisons the world. Echoes of the Sundering is a 1-5 player cooperative, open-world, deck construction adventure taking over 30 hours to complete. Players will create a party of heroes and explore the valley through a beautifully illustrated map book. Along the way, they will face dynamic, narrative-driven encounters and should they succeed, will grow in power gaining new cards to add to their deck and new items to complement their play style! The story reacts to players' decisions and no two play-throughs will be the same! -description from the publisher
