With an ever expanding clan and lair, Setebos and Lysithea found it necessary to recruit more dragons to help with their scientific endeavors. As a native of the Stormcatcher's domain, Prometheus was just the dragon they needed for the job. He often lends his Storm Seeker familiar to Lysithea as an aid in her weather predicting research, and he is especially talented at finding ways to circumvent any problems that Setebos runs into while working on an invention. Spiral dragons are known for their high energy and being a lightning dragon only means he has even more than most spirals. If his two partners get tired and need a rest, Prometheus is more than capable of picking up the slack until they're functioning at full capacity again.
