We are in the middle of an Update to the 2nd Age book Revelations and over the next couple weeks will be wrapping these up. These updates will cover questions, updates, and errata we want to make certain gets into the 2nd Age book before going to print.
We are digging through the forums and checking questions directly from there to make certain we have them dealt with and clarified in the update. So if you have some questions regarding the 2nd Age Revelations, its the most excellent time to post up in the forms if you have not already.
As April approaches the Realms of Gaia will be removed as a free download and will become a part of the Birth of Genesys included when people purchase the book digitally or a physical copy.
