The fallen mountaineer bears a standard of Ironforge. Perhaps she was scouting, or making a doomed charge. Either way, the standard has been cast down and trampled. The mountaineer was hit on the head so hard that her helm was knocked off and she was killed outright by a trogg, likely with a spiked club. The trogg that killed her is probably still nearby, and likely remembers the banner. Raising the banner of Ironforge once more may call it out.
