Derot shared the information on the potions with his merchants and employees before sitting down with Zach and writing down the details of their business agreement. They divided the profits, responsibilities, and objectives fairly.
Derot and his merchants were in charge of sourcing supplies and distributing and selling the potions and creations of Zach's alchemist. In reality, it was something any merchant could do. A third of the profits was theirs. If they wanted to earn even more, they would just have to sell more, buy better but cheaper ingredients, gather sponsorships, and so on.
Zach's alchemists produced common potions but also potions that others in the Empire hadn't even heard of. Those kinds of potions wouldn't be popular at once since they were an unknown. And unknown potions had unknown effects and side effects.
