Humans have been showing up in Equestria for centuries in enough numbers to have a stable population, but few enough that they only count as a minority.

They don't feel like the Equestrian government is doing enough to cater to their unique needs and feel isolated in society.

This charismatic psychopath rallies the humans under him and convinces them that they should be the ones in charge and proceeds to beat the ever loving shit out of dissenters.

What chaos will be wrought when Senator Armstrong tries to take over Equestria?
