Cheerful and determined, Vena is a consummate lover of all things mechanical. She is as passionate as Tevi about tinkering with machines and spends all her money on R&D, to the point of subsisting on a diet of foraged foods (and weeds). Vena sees Tevi as a rival and works hard in the hopes of one day finally defeating her. Until then, she hopes to improve her gadgets while keeping an eye on Tevi's adventure. Not out of any concern, of course, but just to make sure her rival doesn't suddenly run away from their eventual showdown!
