Worldbook: Nine Alternate Realities

Publishers' blurb:

Starsong takes you near the Singularity to a world where a human can become a whale, or a blanket. Northgate City gives you the chance to be a superhero in a vast metropolis. Gothika and Fantastique explore the dark and benevolent side of Steampunk in a world which begins with Viceroy Lincoln's funeral. Doom of the Mech Empire has Bronze Age alien electroforms, and a Human Stellar Empire at war with alien space monsters. Heartwar allows one dreamer to change the world at night, and to be pursued by spy agencies in the day.
