Ambassador Jerrikar

           Ambassador Jerrikar is a Satyr that wonders around in Shadowmoon Valley. He can spawn at up to 5 different locations, usually all of the locations have Blood Elfs or Naga's inhabiting them. If you're farming or looking just for him, I'd recommend hanging around the Dragonmaw Fortress expecially if you need Netherwing Reputation.

           Another farming option would be Eclipse Point, if you need Scryer Reputation. Every 10-15 minutes mount up and check all of the areas he can spawn, kill a few mobs hang around for a bit then continue on. He has roughly a 1 hour respawn timer, so you shouldn't have too much trouble finding him.
