The voices, oddly enough, seem to be yelling in orcish... and as you swoop closer, you hear at least one of them go silent. You can't quite see to where the fighting is, but as you hover just above the fog, you hear the sound of a single horse galloping wildly in roughly your direction, in a path that will likely take it directly below you pretty quickly. Meanwhile, from the site of the fighting, theres an angry, feral sounding roar, and another one of the voices goes silent.
