Path of Exile has been prevewed at IncGamers, who look at Act III:

The Battlefront

Outside the Solaris Temple, the Ebony Legion wages war against a mindless army of floating, red tapestries known as the Ribbons. The shredded remains of soldiers and Ribbons alike litter the ground about the makeshift fortifications and burning incendiaries that sketch the fluctuating front lines of the ongoing battle.

By summoning a massive thaumaturgical barrier at the end of the bridge, the Legion have gained control of the only means of crossing the great river that divides the city of Sarn. It also provides them a secure foothold for their invasion of the Temple.
