The original plot proposal - I don't know where to find a version online right now and it's not mine to upload - called for four artifacts to locate and unlock an ancient enchantment that would bring Atlantis back to the world. This was considered very bad, and was revised. The final revision to the plot proposal was
Harlequin's Gambit, which I wrote, and you can find it
here. The gist is that instead of finding Atlantis, Frosty & co. were scrabbling to uncover timecapsules filled with Atlantis' magical knowledge. This was to help lead into a new magic sourcebook called
High Magic, written by Jennifer Harding and myself. When I terminated my drafts, I pulled about half the book - it was my understanding at the time that Jennifer Harding and Steven McQuillian would be finishing it up on their own, probably revising the plot to work with their already-written drafts. I since heard that line developer Jason Hardy was unhappy with this - I don't know his reasons and won't guess - and it's apparent that he's since decided to go a different way with
Artifacts Unbound. There was a solicitation for the book up, but apparently it's since been removed.
So to answer the
original poster's question: I dunno. Maybe. It's entirely up to the writers of the new book and the direction the line developer wants to take it in. The book that I was working on was going to end with a major magical paradigm shift, but not so much in there being more magic in the Sixth World but more magical knowledge being available to everyone. At the end of
Harlequin's Gambit, Frosty was going to seed the magical knowledge onto the Matrix. Learning blood magic was going to be as easy as downloading a torrent. Obviously, that's unlikely to happen now.
