Artificial tieflings are a species created by Alchemilia Corporation by forcefully fusing the cells of a tiefling with unwilling humans. The progenitor of all Alchemilia artificial tieflings is the Alchemilia officer Galina Nabi.
Artificial tieflings appear as humanoid creatures with elongated limbs and augmented height. Their skin tones range from a pallid grey to a pinkish red color, and they have vestigial bumps on their head where horns would grow from a demon's. Due to issues with sensory overload, the artificial tieflings are fitted with mechanical blinders that filter their vision. They also wield other cybernetic augments for combat purposes, such as arm-mounted drills or large claws.
After the tiefling Galina Nabi was conscripted into the Alchemilia military, the company's genetics department took notice of her extraordinary pyrokinetic abilities and superhuman resilience. Following tests on compatible Alchemilia prisoners and paid volunteers, it was discovered that her uniquely powerful musculature could be replicated. The mass-production of artificial tieflings became a priority, dubbed Project Voight by the genetics department. Gabriel Alchemilia and the other chairmen took interest in the project, seeing an efficient and cheap way to replace androids and foot-soldiers.
Due to the nature of the regular experiments done on Nabi, her mental state slowly deteriorated as more tieflings were produced.
