The Red Crystal

Objectives
Travel east of Auberdine and look for a large, red crystal along Darkshore's eastern mountain range. Report back what you find to Sentinel Glynda Nal'Shea in Auberdine.
 * Locate the large, red crystal on Darkshore's eastern mountain range

Description
Hostile moonkin roam in ever increasing numbers to our east. They once were thought to be gentle, almost mystical creatures. While some continue to hold reverence for them, the safety of Auberdine forces me to keep a more realistic view.

I've received reports that moonkin are being drawn to a large red crystal along Darkshore's eastern mountain range. No one has any idea what that crystal is, or even if it really exists. I want you to locate it over there and report back to me what you find.

Reward
You will receive:

Completion
So the crystal exists, &lt;name&gt;? Fascinating... anyway, your task has been well executed; good work!

What exactly is this crystal? This is but a single question in a sea of questions. Another question that comes to mind is why the moonkin would be drawn to this object? Is the crystal benign in nature, or does it hold a more sinister purpose?

I have many more questions, but we're going to need to examine that crystal closely to get some answers.
