The Army of Saradomin (abbreviated AoS) was a clan who the Triumvirate had a serious conflict with in 2010, during the early days of the Triumvirate. The conflict is known as the Army of Saradomin Cold War. They launched several attacks on the Triumvirate most notably attempts to infiltrate and take down the union. The war involved a misunderstanding on Army of Saradomin's part, over-expansion of the Triumvirate into interfering in foreign clans, and control of the RuneScape Clans Wiki.
The war was concluded in late May of 2010 with the Triumvirate as the victor.
