When Zola "Heterodyne" first appeared✣ in Mechanicsburg, she made her speech in the town square standing on the base of her "father's" statue, which was surrounded by her minions. This is our first glimpse at the band of redshirts cheerfully dubbed by some "Zolamooks".
They wear distinctive uniforms — extremely tall stovepipe-style hats; long black sleeveless coats with multiple pockets (something like a modified duster coat, and a high collar with a Heterodynetrilobite brooch; grey-and-charcoal-striped longsleeve shirts; grey trousers; and very dark goggles. The hats seem to have different devices or apparatus fastened to or sticking out of them. (Good cosplay material here.)
