Bright Hill is the national Presidential Palace of the Osean Federation. Located in the Osean city of Oured, this is the site where the President of Osea works and makes decisions regarding the Federation. During the V2 Nuclear Missile Crisis at the end of the Circum-Pacific War, the Yuktobanian Prime Minister Nikanor and the Osean President Vincent Harling made a speech to both the Osean and Yuke civilians and military personnel, convincing them of dropping their weapons & joining their once-enemies. This speech made most of the Yuke & Osean soldiers on the battlefield doubt their leaders, which fulminated in the beginning a new alliance with the Osean military. Following that, several Yuke soldiers across Yuktobania & Osea joined their counterparts, however the greatest example of this reborn alliance was the Battle of Sudentor, where hundreds of soldiers from both sides, coming from air & ground alike cooperated with each other, not excluding the mysterious Razgriz Squadron.
