Welcome to Talislanta Incognita, an exotic fantasy setting from the 1980s inspired by the Dying Earth & Tschai novels of Jack Vance, the Zothique stories of Clark Ashton Smith and other sword & planet stories like John Carter of Mars and A Voyage to Arcturus. It's a post-apocalyptic world filled with strange magic, unusual races and richly-described cultures.

If you're interested in reading about it, all the books for the game have been made legally available for free on the official Talislanta website by Stephan Michael Sechi, the game's creator.
