Project Homonculus is the sequel to A Dragon's Treasure, taking place chronologically after/during SG2. It follows Sable's attempts to make a body for Fafnir, his foray into terraforming magic, research into the bonding ritual, and of course, his evolving relationship with Drakan.

Throughout A Dragon's Treasure, Sable was forced to confront the growing problem of his sense of inferiority and complacency towards dragons. In the end, he realized that him constantly submitting to dragonkind wasn't doing any good, either for himself or for Drakan.

After resolving himself to treat Drakan more like a regular person, and his promise to her that he would be more proactive rather than just going with the flow, we now have Project Homonculus.
