Some novellas existed even before the #okalrel saga books began coming out. Golden Souls was first written by Lynda Williams c. 1999, and released on the Reality Skimming Blog of that time as a serial with illustrations by Richard Bartrop.
It tells the story of Amel's introduction to fabled Demora, world of the Golden Demish, back when he was a disgrace. And established the character of Princess Dela, who later appears in the saga books.
The current incarnation of Reality Skimming will be re-releasing Golden Souls with the original Bartrop illustrations in the fall of 2021.
