Since its sudden birth the city had expanded, swallowing up acre upon acre of the surrounding grasslands and drawing thousands into its domain. Hardly built on the most advantageous ground, miles from the open waters, decades from the mines at the mountain summits, it yet remained the only settlement of note on the isle. This sprawling mass of a city, once a compact kingdom, was now the keystone of the Castilian Empire.
