I actually own only the dead tree copy of this campaign setting, so I’ll break my usual format for this review. The Realms of Twilight Campaign Setting comes as a massive hardcover book, including two pages of character sheets and 1 page map. After a page of editorial and a page ToC, we get 2 pages introduction and overview of the contents. After that, we get introduced into the world of Relistan. One of the things you immediately notice, is that the b/w-artwork is stunning and ranks among the best you can find in any 3pp-books.
