Sumala Volos, known as the Thinking One, is a Marnish engineer whose writing explores petroleum as a source of heat and whose inventions include the lightning rod. Her book records lightning-rod testing locations and informs Thessa’s notes and instructions for the phoenix channel experiment. When she appears, she hops down from an ox-drawn wagon, tastes the air, and gathers Montego and Kizzie close.
Description
Sumala Volos is shown lifting her head toward the northwest, clasping her hands behind her back, and rolling up her sleeves. She stretches out her tongue to taste the air, then hops down from an ox-drawn wagon. She carries Montego on her shoulder and Kizzie in her other hand.
