Tinfoil hat theory regarding Noxus and Mordekaiser

So we all know that the Immortal Bastion, Mordekaiser's old Fortress and center of his empire is now under Noxus' control and serves as its capital. This lead me to question just who the Proto-Noxians might have been... and then it hit me.

Mordekaiser is several centuries old and what was once his empire included both Noxus and Demacia. The fall of the Murder emperor might have freed those outer areas (Demacia and Co.) from his grasp but what if Noxus' civilization is based on Morde's philosophy. His people/subordinates were influenced by the Tyrant's doctrines and through the ages the source of "The Strong take it all" philosophy ws lost to time, nobody remembering the dark Revenant who ruled with an Iron fist.

It might just explain how stark the differences between the other Nations seem to be, Noxus still clinging to Morde's philosophy and being vastly influenced by the culture he governed at the peak of his power.
