Cinderhome is a small community a dozen miles to Hearthglen's east. It is controlled by the Scourge. In an attempt to expand the Scarlet Crusade’s influence, Taelan Fordring once led an expedition to retake the small community. He and his men slew the undead, but before they could bring in settlers and reinforcements, a Scourge host arrived and laid siege to the village. Tirion Fordring, observing the whole endeavor, and worrying for his son, sent heroes to break through the undead line to save the Crusaders within.
It is speculated that Cinderhome is infact Northdale in WoW, since you are sent here by Tirion in the quest to recover a flag known as the "Symbol of Lost Honor" and in the quest description Tirion states that Taelan and the Crusade did indeed attack the village and tried to reclaim it from the undead (without any luck however), much like Cinderhome.
