Jorus the Cobalt Netherwing Drake

After getting exalted with the Netherwing, and completing Lord Illidan Stormrage you can pick a quest for a free netherdrake of whichever color you like, and buy the other colors for 200g each.

Level 70 players will begin their journey to exalted reputation by picking up the quest chain offered by Mordenai, a blood elf wandering the surface of the Netherwing Fields, in the southeast corner of Shadowmoon ValleyGrind the daily quests for the rep, takes a few weeks but quests are fast when u know them. Bit of gold from doing them too. Players are introduced to the Netherwing faction at 0/36000 hated reputation, and must be exalted to receive a Netherwing Drake. The quest chain and reputation grind is a mostly solo endeavor involving quests that can only be completed once daily, a 5-player group quest on the way to neutral, and daily 3-player group quests after reaching revered. A flying mount is required for this reputation grind, and 300 riding skill is necessary to advance past neutral. . The quest chain begins with the quest Kindness. Completion of this quest line will provide an instant reputation boost to neutral. The eggs found in the caves (mostly) and outside the area (rarely) are worth 250-300 rep points each.

It takes about a week or two to get exalted and once exalted you pick one drake as a reward for free then if you want to buy the others you go back to Shadowmoon Valley to purchase them :) And they're only 180 gold each :D
