Archmage Pentarus

Archmage Pentarus is a member of the Kirin Tor who resides in Dalaran. He is a huge fan of the Dalaran Destroyers and loves eating with  while attending their games. He is standing in Krasus' Landing waiting to travel to watch the game, but he doesn't have enough food for the trip. He also offered to fund Hemet Nesingwary's latest expedition to the Sholazar Basin, expecting to receive rare samples of exotic plants and crystals in return, but hasn't heard any word back from him.

He starts the quest:

After accepting this quest, players may talk to Pentarus to board a flying machine and fly through a portal to Sholazar Basin. He will continue to offer this service until the player makes sufficient progress in the quest chain that unlocks the flight point at the Nesingwary Base Camp. (He stops offering the flight by the time is completed; however, it might be an earlier quest in the chain that triggers the change.)
