"For hundreds of years, the Aurumium mountain has been mined under Zamorah. Early on, they broke open a rock room and moved the river so that it went through the mountain instead of around the mountain. This was done to facilitate transport to and from Zamorah. Over time, a port with an extension of the city was built in the rock space below the city. The only way to enter Zamorah is from the river and the elevator that goes up to the city. "
