We've been drip fed information about the next game in line with the Dragon Age series ever since it was announced. We can't wait to hear more about Dragon Age 4, but updates are still quite slow-going. The most recent update, however, is pretty exciting. A new BioWare art book has revealed Dragon Age 4's official setting.

It's called Tevinter, and it's a part of the world of Thedas. This information is taken in BioWare: Stories and Secrets from 25 Years of Game Development.
