GAIA Machines

The machines of the terraforming system take inspiration from animal biology, primarily from vertebrate species (the exceptions being the Shell-Walker and Control Towers). The typical machine design features a chassis composed of darker alloys, synthetic skins, and fiber-optic cables, with lighter alloys serving as armor plating for vital components and synthetic muscles. The logo for the machine's respective Cauldron will be located in multiple places along the body, and armor plating is sometimes lacquered (the Fireclaw's armor plating is dark red). Due to their respective purposes, not all machines have jaws and the ones that do generally have split mandibles. The machines vary in size from slightly larger than humans to as tall as ten stories.

With the exception of the Tallneck and Control Tower, all machines have visual sensors, arranged in either a monocular or binocular fashion.
