Cat is a wannabe merchant who specializes in procuring in-game valuables to sell for real money. He's a cunning trickster who wriggles his way out of trouble thanks to his quick wit and his trading talents, and his credo is “Anyone can be bought provided the price is right." He starts from scratch, using every opportunity to advance his plans. The first book in the Rogue Merchant series, The Starlight Sword is the story of this common trader’s rise to becoming the world’s newest legend, the most famous merchant in the entire Sphere of the Worlds—a worldwide multiverse comprised of hundreds of worlds, from horrible Infernos ruled by Demon Lords to mechanical worlds inhabited by sentient constructs.

In the Sphere of the Worlds, gigantic markets have sprouted at the crossroads of trade routes, and players use astral ships to travel between worlds to avoiding having to venture into the perilous underground tunnels of the Endless Paths. Dozens of powerful clans share this delicious pie, scheming or waging wars against each other. A classic might-and-magic-style LitRPG series with elements of manapunk, the Rogue Merchant series focuses on the economics of this game world, including various trade methods, such as regular and auction trading, as well as social and political interactions between clans and players. There's plenty of intrigue and espionage, betrayal, trade wars, besieged castles, and epic air battles of flying ships!
