The Six Voyages of Lone Sloane, Volume 1

It's been 800 years since a catastrophic event called the "Great Fear". Lone Sloane, a rebel and a troubled space traveller, is captured by an entity called "He Who Seeks", after his space ship is destroyed. The entity transports him to different dimensions, where he must fight for his life, as he finds himself caught in an intergalactic struggle between space pirates, gigantic robots, dark gods and other-dimensional entities.
