Tirgrad fluff

Tirgrad is a nation populated by homunculi with the power to shape their own flesh and bone. Upon emerging from their birthing vats in an ancient laboratory complex built deep withing the earth, the first homunculi of Tirgard. While they were unable to comprehend the vast majority of the technology within the labs, they were able to discovered the technique to produce new homunculi from their own flesh. Leaving the complex along with their newly created offspring, the homunculi set off to discover more about the world around them. What they discovered was often unpleasant. Their ability to sprout bone blades and army saved the homunculi's lives on many occasions. Fearing for the fate of strange beings such as themselves in a potentially hostile world, the homunculi resolved to found a nation of their own. They named this new nation for the laboratory complex from which they emerged, 'Tirgrad'.
While often terrifying in appearance, particularly those in combat-form, the homunculi of Tirgrad are not malevolent. Rather, they are coldly rational and deeply curious, with an deep drive to improve on their body-shaping abilities. Tirgrad itself is ruled by the original homunculi from the old lab, who hope to guide their creations as they continue to refine their abilities.
