Hearthglen Woods

The Hearthglen Woods is the location where the human paladin Tirion Fordring found the orc Eitrigg. Mighty oak trees are here. Tirion was the governor of the prosperous Alliance principality of Hearthglen, a large forested region nestled at the crossroads between the towering Alterac Mountains and the mist-shrouded shores of Darrowmere Lake.

Later, Lord Commander Saidan Dathrohan led a detachment into the Woods in search of renegade orcs.

Speculation
In the game, north of Hearthglen is a closed area and it could be the Hearthglen Woods.
