This quest was marked obsolete by Blizzard and cannot be obtained or completed.Kill 10 Saltstone Basilisks, 10 Saltstone Crystalhides and 6 Saltstone Gazers for Trackmaster Zherin on the Shimmering Flats.
After the big crash with the goblins' Red Thunder racer and a basilisk, Kronkrider hired me on to take care of the track. I don't know what all the animals out on the flats are feeding on to grow so big, but we have to be careful to thin them out so they won't wander onto the track when a race is going on.
Tell you what. If you want to go out and make a little profit, go out and remove the basilisks from the area.
