The relationship between the 3-member regiment and the gilded brigade

hello, what is the relationship between the 3-member group and the gilded brigade? The relationship between the 3-member regiment and the gilded brigade is a mercenary institution. In the original god of the game, the gilded brigade is an immigrant from the ancient civilization in the desert. It does not join any national forces, but strives for a living with its own wisdom and strength. They also mastered the heritage of some ancient civilizations as the last deterrent to deal with the crisis. Among them, the oldest and largest gold-plated brigade is the 3-member brigade, which is mainly responsible for the defense work of Sumeru City, and most of the work is issued by the Imam Institute.
