Gastro Zimirvox, more commonly known as Trade Prince Zimirvox, is the current ruler of the Sparkcog Cartel. Under his leadership, Sparkcog has grown into a vast trading empire from Kezan and far beyond, becoming more powerful than it has been in centuries. He is regarded by many Sparkcog historians as a risky, but successful economic speculator and perhaps one of the greatest Trade Princes to come to power in a few centuries.
