The Beginning Part 1 is the first episode of the 2002 He-Man and the Masters of the Universe series.
The exiled warlord Keldor tells his forces that he has created a device that will destroy the "Mystic Wall" that keeps him and his followers out of Randor's kingdom. Inside the castle walls, Man-At-Arms receives a telepathic message from The Sorceress that the time has come.
The episode starts out with The Defenders, led by Captain Randor entering the Hall of Wisdom to alert The Elders that Keldor, will soon attack with his evil army. The Elders tell Randor that his troop will win and Randor will be king of Eternia. Just then, Keldor and his forces break though a wall of the Hall of Wisdom, and a battle ensues.
Randor manages to defeat Keldor, so Keldor throws a vile of acid at Randor, who blocks it with his shield. The acid instead splatters on Keldor and his forces retreat.
Here, Keldor tells his forces that he has created a device that will destroy the "Mystic Wall" that keeps them out of Randor's kingdom. When they get to the Mystic Wall, they trigger the device but all it produces is a mere crack in the wall.
Keldor's forces are confused, as they assumed that the device would break the wall completely, but Keldor explains that now they know where to strike.
Sometime later Man-At-Arms is watching Prince Adam and his daughter Teela, who are battle training outside, in the courtyard. Without warning Man-At-Arms receives a telepathic message from The Sorceress that the time has come.
Understanding, Man-At-Arms tells Prince Adam that he needs to accompany him to Castle Grayskull. Once inside Castle Grayskull, they meet the Sorceress face to face and she tells Prince Adam that all of the Elders of Eternia's power lies within the wall of the castle and that he needs to acquire this power to become He-Man the protector of Eternia. Prince Adam doesn't believe the Sorceress and leaves to find Randor's castle in the grip of chaos..
