Prior and to a certain point during the events of the Firestorm Conflict, the group was composed of five generals who had survived the aftermath of GDI's victory over Kane. The group was dominated by two generals - Anton Slavik (in the middle of the right photo) and a man known as Marzaq (at the right of Slavik), both of whom tried to establish total control over the group and enforce their concept of what the Brotherhood should become in the second interregnum.
Third Tiberium War
Following the Firestorm Conflict and the return of Kane, the Inner Circle was reestablished and regained its role as advisors to Kane and his most loyal followers. The Inner Circle during the Third Tiberium War included Brother Eamonn, the aforementioned Nod commander, an unnnamed advisor, and Kilian Qatar before she was framed by Abbess Alexa Kovacs. After the conclusion of the Third Tiberium War, Kane's most trusted commander became a member of the Inner Circle.
