Gruegel is a city in SaGa Frontier 2, and under the rule of King Sui of Na. Gruegel is the capital of Na, a country located on the Southern Continent. The city sits next to the Vogelang Canyon and enters out onto the Grand Desert, home of an ancient Megalith. Despite it's vicinity to a Megalith, the Southern Continent (by large) has no Quells, and the people have to rely on custom made Tools.
Gruegel is a great place to buy/convert Chips as well as purchase custom made Tools, providing you have the money and Chips to do so.
