A Homunculus, or homunculi in plural form, refers to a fully developed, albeit tiny, being that resulted from the practices of alchemy and scientific endeavors. In the era of the Empire, Sly Moore, an advisor to Palpatine, initiated scientific investigations aimed at unraveling the secrets of existence. The scientific experiments that her scientists conducted yielded a multitude of malformed homunculi, characterized by additional heads and incomplete limbs. Trioculus represented the ultimate and completed outcome of that particular experiment.
