Hypercapacitor Gizmo

I am the only survivor from our caravan attack by the centaur! A rare yet mighty panther is guarding my best gizmo, which is around his neck. Hah! Even the centaur tremble in the presence of this ferocious beast!$B$BHere is the key to the cage. They took everything there, but left him alone. Slay this beast and bring back my hypercapacitor, and I shall reward you.$b$bThe wrecked caravan is just north of here.
