Fires of Heaven. Space opera writ large.
It is the 23rd century and humanity is the center of a loose and expanding alliance of worlds, including several alien races. Threatened from within by corruption, and from without by the militaristic Vorn. Fires of Heaven (by Patrick Sweeney) is the largest EABA supplement to date at over 420 pages, with an interstellar atlas, corporate profiles, starship design and combat and more (and kudos to Jeff Alberts for the very nice cover). You need EABA, of course, but otherwise it is a complete SF setting in one massive volume that you can print out individual sections of as needed. You can download a 24-page sample here.
Because of its sheer size, we recommend that Fires of Heaven either be viewed on your computer (or tablet) or purchased as a print on demand version. Printing the full rules yourself would be a major undertaking, but you could just print key bits and reference the rest from your computer. If you are interested in a print-on-demand edition to keep from wearing out your printer, check the Guild of Blades link on the main BTRC page. We're working with them to have it available as a two-volume set.
