Ugellas (ユージラス), officially known as the Independent State of Ugellas (ユージラス自治州),[1] is a state[note 1] located in western Usea. Ugellas purportedly shares a border with the Republic of Amber and the Federal Republic of Erusea.[1]


Prior to 1996, Ugellas had remained under threat from neighboring Erusea, whose military had been mobilized near the border shared with Ugellas and Amber. In response to Erusea's sabre-rattling, the Federation of Central Usea (FCU)—in conjunction with the IUN—stationed troops near the border to prevent the spread of Erusean influence. However, following the announcement of the Ulysses asteroid's approach, the FCU withdrew its forces to protect the Federation's interests at home and promote cooperation between all nations, including Erusea, in dealing with the Ulysses threat.[1]

Due to its close proximity to Erusea, Ugellas was likely under Erusean control for much of the Continental War until late 2005, when ISAF's counteroffensive forced the Erusean military to withdraw.[2]



  1. Contrary to the official English term "Independent State," the term used in Japanese to describe Ugellas (自治州 Jichi-shū) means autonomous administrative division. The implication is therefore that Ugellas is not actually a sovereign nation, but rather an autonomous territory of another nation. The same term is later used to describe Shilage (シラージ自治州 Shirāji jichi-shū) in the Japanese version of Ace Combat 7: Skies Unknown.
