Tad Williams, the author of the original Otherland quadrology, has written a new novella in that world. What does this mean for players of Otherland? Well, part of the novella will be available in the game. Obviously, the entire thing can’t be present there, but some of it is; the official post on the matter explains that it’s a bit like the short story which would eventually grow into the novella. And yes, that means it’s a new story about the game world in the actual game world.
But there are going to be fans of the books who aren’t necessarily interested in playing the game, and thus the developers are planning to introduce a new “Social” character type to the game. These characters have no combat abilities or progress, but can bypass all of the usual starting zones to simply start the treasure hunt for the story; players can later convert these characters to normal characters if so desired. Not a bad cross-promotion all around, really.
