Sam Wiggins was a very successful Merchant.
He started as the leader of a caravan that traveled between the different cities of the Kingdom of Gweliven for trade and commerce.
In fact, he was so successful that many of the High-Ranking Nobles of the Kingdom of Gweliven patronized his services. With his strong portfolio, he even received an offer to become the Head of the Merchant Union in the Dungeon Town of Wisp Tree Town.
This position held considerable power, allowing him to decide which businesses were given permits and certifications to operate.
Simply put, he had complete control over the trades happening inside the city, which would make any Merchant wish that they were him.
This was also the reason why Twilight Rain spent many resources in order to win him over and become one of the Honorary Elders of their Guild.
With this newfound backer ready to crush any opposition who wished to stand in his way, Sam felt that he was the Underground Emperor of Wisp Tree Town.
