Homunculus
From the White Wolf Wiki, the most complete White Wolf reference
One of several kinds of magical servitor fashioned for the purpose of serving some dark, twisted sorcerer. Homunculi are typically small, man-shaped flesh creations: the homunculus is a staple work of the mystical art of Alchemy, but certain vampiric blood magics can conjure up a homunculus from body parts. Homunculi can be man-shaped, cat-shaped (see "Witchcat,") or thoroughly bizarre creations, such as those created by the Getsumei power "Channel of Hasu-Ko" and the Crúac blood ritual "Bleeding the Tarantula."
