Life-Essence Extraction Device

A jagged, metallic ritual apparatus with skeletal arms that hum with violet energy when active. Its twisted metal frame terminates in glowing fingertips that pulse as they siphon life force. Weng-Chiang uses it to bolster his decaying form, the air around it shimmering with stolen vitality. Leela and the Doctor recoil at its touch, recognizing it as a conduit for forbidden power.
