So, we know Sjohn did the Chelarian material (with a template by James Maliszewsky), J. Snead did the Rigelian, Rigel V, and other Rigel Sector planets stuff, and Hite was developing... what else was in the book? Who else was writing for it?
Of all the unpublished material, what I've seen has certainly been the coolest.
EDIT: Was it Sky Princes or Sky Pirates?
