Orbments
Mechanical units powered by a mysterious energy known as "orbal energy".
Inside each orbment are circuits made of septium, a crystallized material.
Depending on the structure, each orbment can produce a wide range of
effects.
Invented about 50 years ago by Professor C. Epstein, orbments quickly spread
across the continent, becoming the foundation for diverse technological
advancements, including lighting, communications, machinery, weapons, data
records, and even airships.
