We defeated Eranikus in Moonglade to complete the Scepter of the Shifting Sands quest for one of our guild members. This was a pretty impressive fight. The first time we tried it, we were helping Darkfire (an Alliance guild). They had a full raid, we had a full raid, and we wiped on it.

This time, it was just our raid, another 10 people or so, and a good strategy, and we bagged him on our first try. In fact, we had him below 20% by the time Tyrande showed up (you've just gotta fight him until she shows up, and then she casts a spell to make him good again).
