Frames is an umbrella term for robotic people. The frames are all humanoid in size and shape, save for a few exceptions. The actual origins of almost all of the frames is unknown.
Frames travel in nomadic style, often alone and can be found in remote, secluded locations. Monastery like structures serve as the home of small groups of frames. As a result of their minimal requirements in life, they take on simplistic lifestyles and seem to have a strange and acute curiosity for philosophy.
Despite their artificial intelligence, they seem to have a kind of biomechanical internal system which provides the power and capacity to host them as an AI. They are however, completely self contained, making it impossible to transfer them like Construct AI.
The physique of frames is relatively human like. A few exceptions can be more diverse, but usually human size and shape. They are no stronger than humans, or whatever humanoid they are designed after, and are not naturally attuned to computers or machines, even as robotic life forms themselves. They are simply people with metal bodies.
