>>40559997 (OP)The jester symbolism I think is self explanatory.
They are there to get a kick out of everything. If something is built, they destroy it, if something is destroyed they built it so they have something to destroy. If you wish they are your friends, when they become your friends they turn enemies. They are true contrarians for the sake of the contrary.
They create action to fend of existential boredom. No morals whatsoever since they are foundation of stability which is exactly what boredom is.
