Skog is a gronn that can be found near Frostwall in Frostfire Ridge in a large cave. Skog's gender is unknown, but the Frostfire Gronnlings are known to be Skog's progeny. Notable among these gronnlings are Gurun and Gruuk. Olin Umberhide first tried to battle Skog, but failed, prompting the commander of Frostwall and Thrall to confront the gronn. Later, Skog's den is turned converted into an Herb Garden and a Fishing Shack.
