Background
The city was located to Re-Estize's east and was west of the Azerlisia Mountains, right near the vicinity of the neighboring Dwarf Kingdom. While the human kingdom had not attempted to forge any national-level ties with the dwarves, this city was one of he few places where small deals were made between the two nations. Ties like these were closely linked to the city's profits.

The Craftsman of Dwarf Arc
During Ainz Ooal Gown's research into the Dwarf Kingdom, he learned that this was the only city in the Re-Estize Kingdom that are known to have dealings with the nation.

The Witch of the Falling Kingdom Arc
After a grain convoy meant to serve as humanitarian aid from the Sorcerer Kingdom to the Holy Kingdom had been taken by force by a citizen of the Re-Estize Kingdom the Sorcerer Kingdom took it as a hostile action. The Sorcerer Kingdom declared war on your country, sending an official document that bore the seals of other countries that approved of the other Kingdom’s actions. Among them was a seal from the Dwarf Kingdom. Though it took the Kingdom time to identify the design as dwarven, since they had no prior official contact from the dwarves for two centuries. The Kingdom's officials had to receive the assistance from Re-Brumelashul with the investigation, and found a similar seal in their own archives and confirmed it was indeed from the Dwarf Kingdom.
