Duke's goal was to keep a low profile; the best stores usually have high foot traffic, and putting his shop in such places would naturally make sales easier, but it would be too ostentatious.
His initial target customers were the mages of Azure Vault City, but ultimately his main sales would be to those adventurers.
With adventurers, he didn't really need a prime location, as they could quickly spread information about him on online forums and other places.
Duke had already learned from Dali that Alchemists were very rare here, especially those who could refine powerful magic potions.
The level of potion-making on this Plane seemed relatively low, and the Level 1 Potion Duke casually produced was already seen as a powerful potion by Dali and the others.
There were no large-scale potion shops in Azure Vault City, only a few well-known Alchemists, but they were far inferior to Duke.
