Anduin steps forward after Wrathion, in the direction of what is now clearly at least partially running water. The snow and frozen leaves of the forest floor crunching underfoot as he walks.

Anduin winces slightly.

"Did the people of Alem share how large this river is?" Anduin asks. Not that they won't be seeing it in another moment or so, but it pays to be prepared. The fact that it is running is a good sign. It has not frozen over completely, the current is strong enough to keep it from doing so. But... Well, a river could mean any number of things, really.
