FFG announced yesterday that The Black Riders and The Road Darkens expansions will be re-released as a single Fellowship of Ring Saga expansion. It will contain all the same player, encounter, and campaign cards the original 2 Sagas had. If you have previously purchased The Black Riders and The Road Darkens there are no cards for you.
For additional details please check out the official FFG release article.
I’m sure this comes as great news for many new players. I have many in the various social groups trying to find Saga expansions and not able to find them. There was some anxiety for a while they wouldn’t get reprinted but those fears can be put to rest.
