There are numerous fan created maps of the 'Verse and several commercial versions. Before it was understood that the 'Verse was a multi-star system, many fans tried to map the worlds of Firefly around a single sun. Hansel Cook was one of many to create a single star system. He completed several versions of his 'Speculative System Map' for the 'Verse. Another was made by an artist called 'colorsmith' who designed a map based on a proposed layout by James Michler.
