In the days of Prince Ump of Er, the tiny hamlet of Er was bonded with the city-state of Pheebor. It is uncertain how the prince met his death in 396 BE, but it was at the hands of the Borpheans. Ump's last recorded words were, "...and that is why the people of Er will never be defeated in military battle, against an enemy of any kind.”

In future years, everyone of the village of Er claimed to have direct heritage with Prince Ump.
