My thought was for the Aerii people, or the bird people, to essentially be the more mechanical type. Not totally steam-power, but elevators and goods transports powered by steam. Both handheld-crossbows and towers that fire very large, anti-seige crossbow bolts. The type that would have to be manned by the larger, stronger humans. Think of a less advanced Dwemer from Skyrim. More of just the elevators and gates and crossbows and pipes.

Anti-siege crossbows? You mean ballista?
