James Lloyd Steam

Ray's idealistic grandfather. The original conceiver of the Steamball, which he succeeds in developing with his son Edward. A difference of opinions with his son Edward leads to friction between them. While Edward believes that science is an instrument of power, Lloyd simply wishes to use it to help people. They both develop distinctly different visions for their ultimate invention, the Steam Castle. It is later revealed that Lloyd intended the Steam Castle to be a sort of flying amusement park, but Eddy scoffed at such a premise, denouncing it as a "fairy tale vision." Edward instead built the Steam Castle as a flying military fortress.
