Man-At-Arms introduces his latest invention, the robot horse Stridor. A meteor shower at the Royal Palace alerts the Sorceress to the return of Morgoth the Terrible. She explains to He-Man that Morgoth was a wizard who sought too much power and was banished to another dimension by the Ancients. They journey to Dark Mountain to prepare for the return of Morgoth.
The Sorceress explains her origin story, which began when Morgoth invaded her small village. Morgoth, with an army of alien invaders, imprisoned the Sorceress, then known as Teelana. A fellow prisoner told Teelana the legend of Castle Grayskull, where hope may be found. She escaped her captors at night and searched out the castle. A voice beckoned her inside, where she found Kuduk Ungol, the former Sorceress. She offered Teelana the power to defend her village, but only if she replaced her as the guardian of Castle Grayskull.
Teelana accepted, and Ungol lowered her into the Pool of Power. Teelana emerged "changed" as the falcon Zoar. The Sorceress liberated her village by destroying the ship controls of the alien invaders and sending Morgoth back to his dimension. In the present-day, Morgoth's symbolic ring of fire appears, and he drops his magic gem into the Eternian soil, placing a force-field around it, which no living creature can breach. Stridor pushes through the barrier and kicks the gem out of the field before falling to Morgoth's blasts. He-Man destroys the gem, sending Morgoth back into exile. He-Man carries Stridor back to the laboratory, where Man-At-Arms' Electrode Thought Monitor reveals that Stridor wants to be free. They release Stridor into the wild moments before the Sorceress returns to Grayskull.
