The engines are supposed to show us where their energy source is from.
Here are the really good ones:
Vivian's engine gets wind energi when the propellers rotate, it creates ether magic the mockingbird becom purple and become alive.
Qingyi's engine is steam power, hot water theme in a tea pot.
Lucy's engine energy comes from a boar inside it.
Caesar's engine is combustion energy, smoke comes out from the pig snout.
