The primary setting of the Angelfyre saga is within the Stelerean Constellation, a tight cluster of fictitious star systems that are mostly (but not all) members of the United Systems.
Angelfyre Destiny takes place in four systems: Alerean, Solfarn, Oreannen, and Stelerean, all United Systems members within the Stelerean Constellation.
Individual details on the worlds and planets are still in progress. In the meantime, you can familiarize yourself with the various star systems within the Angelfyre Destiny story.
Disambiguation: The term 'Solar System' within the Angelfyre Universe refers specifically to the one we as Homo sapien inhabit, and is not a general term to describe 'Planetary Systems' as is common in other works of science fiction. Also, 'Star Systems' are used interchangeably with 'Planetary Systems', even though, from a scientific standpoint, they are two different things.
