Gather 12 Motes of Myzrael, then bring them to the Iridescent Shards in Drywhisker Gorge.
My name is Myzrael. I am a princess of the earth, and my captors, the giants, have trapped me deep beneath the Arathi Highlands. These crystal shards are the only way I can speak with the surface world.
Please help me. Allies of the giants, the Drywhisker Kobolds, have a shard like this one in their Drywhisker Gorge, to the east. To power the cluster, you must gather Motes of Myzrael from the kobolds and apply them to it.
I beg you, <name>, aid me!
