Gregan Brewspewer

From WoWWiki

Gregan Brewspewer is a level 45 quest giver located in a small camp just west of the road south of the Twin Colossals in the contested territory of Feralas. If you look on the map, he's right on the first "T" in words "The Twin Colossals" (coordinates 45,25).

Gregan is an expert with plants, and he doesn't like to spend much time in towns and prefers to stay out in the wilderness. He is friendly to both Horde and Alliance.

He starts the quest  [52] Haze of Evil (Dungeon). He is also part of the Linken chain-quest; specifically, he is required for the quest The Videre Elixir.
