The Charlatan.

There are soldiers in the fortresses but they are not the main fighting force. Each fortress can churn out golems in the thousands to field an army. The fortresses are armed to their metallic teeth. This is a force ready for war but they only surrounded the fighters. They didn't shoot their ranged weapons but they took aim. 

The fighting stopped immediately. Every origin paused in the air. The sight and the feeling of having matter disruptors and energy destabilizers with other assortments of deadly cannons trained upon them froze the origin gods.

A loud voice rang out from each fortress and said the same thing. "Cease all Hostilities. This is the patrol guard of the Virut plane. Please leave if you're not an indigene of this plane or explain your purpose to the racial council of the plane. You have a minute to decide. After which, the racial council will be forced to intervene."
