The Forest Guard is an elite Erathian fighting force that appears in Heroes III and Heroes IV. They are experts in guerrilla warfare, and are described as "Erathia's eyes and ears." The Forest Guard often fought in joint operations with the armies of AvLee.
After the Reckoning, the Forest Guard became a part of the elven nation of Aranorn. During the Aranorn Civil War, most of their members chose to side with Lord Harke, their former commander, over the new Elf King Elwin.
