From WoWWiki

The Nethander Stead is a farm just east of Southshore. It has been overrun by Mudsnout gnolls, and is the only location that gnolls of this tribe can be found. Giant white mushrooms called Mudsnout Blossoms grow in its abandoned fields. These mushrooms are of particular interest to Apothecary Lydon to make a deadly brew called the Elixir of Agony.

Old Hillsbrad

In the Caverns of Time instance Old Hillsbrad Foothills, this stead is not overrun by gnolls, but is being handled by Hillsbrad peasants.
