OriginThe first worgen were in fact derived from an ancient druidic sect known as the Druids of the Scythe who worshiped the wolf Ancient Goldrinn. The chosen shapeshift form of these druids was the worgen form, but these druids lost themselves to the form's savage nature and descended into feral behaviour. The other Druids agreed that they must be locked away, and thus put them into eternal slumber deep beneath a tree in the Blackwald.
Actually cursed druids from Azeroth's ancient past, the worgen were released from their prison in the Blackwald by several tamperers over the recent years. Unfortunately the methods of removing them from their prison do not appear to be reversible, leaving the insane druids unfettered and unrestrained. For a long time, the worgens' origins remained a mystery, and their home was thought to be another dimension, or another world.
Ur, a mage of Dalaran, did research on worgen but never summoned them. He found out that the worgen seemed to hail from a dark and treacherous world, from which there was no corner which was truly safe. Velinde saw the worgen battle an unflinching enemy in a vicious war; the Lords of the Emerald Flame.
Frustrated by the destruction of Dalaran by the Scourge and against the advice of his peers, Archmage Arugal elected to summon an army of the extra-dimensional entities by using Ur's research. The summoned worgen fought against the undead armies, but quickly turned on the wizards themselves. Driven mad with guilt, Arugal adopted the worgen as his children and retreated to the newly dubbed Shadowfang Keep, where he then cursed the village people of Pyrewood to turn into worgen whenever the sun went down.
At approximately the same time, the night elf Sentinel Velinde Starsong was given the task of clearing Felwood of demons. She prayed to Elune and was granted a magical scythe which could summon worgen. Using the Scythe of Elune, she summoned a very large number of the creatures to fight at her side against the demons. Later Velinde began to notice that some of her force were unaccounted for. It was as though the Scythe of Elune no longer required her presence to perform the summoning process. Perplexed by this development, she ordered the remaining worgen to remain at the Shrine of Mel'Thandris in Ashenvale and began to search for Archmage Arugal, whom she had heard also summoned worgen. From that point on her fate became a mystery, but it was rumored that she was killed in Duskwood and lost the Scythe of Elune. Black Riders from Deadwind Pass came to Duskwood looking for the Scythe and murdered a family of farmers in the search to find it.
Wrath of the Lich King
In World of Warcraft: Wrath of the Lich King, Arthas has discovered Arugal's activities and has brought him back from the dead to work for him. This also means that there are a lot of worgen allied with the Scourge in Northrend and in particular, the Grizzly Hills.
