Ok so Roman Empire fell.
There was so much chaos that just 3 villagers left.
They promise among themselves to not use their hunting arrows on their human foes ever again.
They build a house with palisade around it that can train mindless clubmen.
They stare at that one person with a horse.
Nobody knows how he got the horse.
Nobody else can do it.
Why he get a horse and we get clubs.
There are mysteries that cannot be solved.
He has a sword. But clubs do more damage.
But wait what are those sheeps searching in the darkness?
