The Airship Isabella is a mercenary ship for hire. Through the use of steam powered generators, augmented by a mysterious essence known only as Aether, the crew travels from dimension to dimension, from time to time, completing jobs, causing a ruckus, and "collecting" goods from each individual world. The crew consists of many a rag-tag personality, but together, they make a family.

On the flip side of the story, ASI is a group of artists, performers, and visionaries who have bound together to create characters who explore the boundaries of the Steampunk community and a menagerie of worlds to put them in. On their agenda: to create art for others to enjoy as much as themselves, to share their knowledge with those who find it of interest, to encourage people who would otherwise find themselves incapable of creating something wonderful to put their worries aside and realize that - with the right knowledge and tools - they can do it too!
