At Snake Mountain Two-Bad is eating when they, again, start fighting. Stinkor approaches and questions why they fight. After they explain that they don't like being stuck together, Stinkor sends them to an old friend of his named Vormus. A friend who deals in magic.
At the palace Man-At-Arms and Queen Marlene are playing a game against Teela and Adam with Sy-Klone and Roboto watching. Eventually the parents lose and the kids celebrate. Seeing the two families saddens Sy-Klone by bringing up memories of his family and leaves. Roboto tries to comfort him by telling him that families continue to add members. Sy-Klone decides to search out others of his family.
Elsewhere Vormus is reading when he is approached by Two-Bad demanding the Spell of Seperation. Vormus gets the spell tablet and upon reading decides not to sell the tablet. Two-Bad grabs Vormus, who drops the tablet, and insists on taking it. On the floor a piece of the tablet with a picture of Eternia cut in half is on the floor.
Two-Bad immediately heads for the first of three artifacts that are needed for the spell. The first one (looks like the letter C) is under the ocean.
He-Man and Battle Cat meet with the Sorceress, who proceeds to tell him about the history of the Triad.
It was created by evil sorcerers at the command of the warlock, Hordak. He used it to separate the planet into two hemispheres, light and dark. The planet, itself, began to separate and realizing he was in jeopardy, ceased the spell and sent the three parts of the Triad to the corners of Eternia. She then tells him that someone is gathering the pieces and must be stopped.
Sy-Klone and Roboto arrive on an island and search the village there. With no one there, Sy-Klone again becomes saddened.
In Subternia, Two-Bad has collected the second piece when he is confronted by He-Man. He-Man demands they stop and return the pieces. Two-Bad drops the pouch containing the pieces of the Triad and blinds He-Man when he goes for the pouch.
Flying back to the palace, Roboto questions why Sy-Klone is saddened over not knowing his descendents, which he has never known. Sy-Klone refuses to talk about it.
Elsewhere, Two-Bad is attacked by a red dragon. Two-Bad throws a gas capsule at the dragon that knocks it unconscious. Two-Bad then collects the third piece of the Triad. He-Man soon arrives and checks on the dragon. Two-Bad heads toward the location for the spell and He-Man pursues on Battle Cat.
In the dark hemisphere, Two-Bad starts inserting the pieces into the slot. When the planet begins to rumble, Bad wants to stop but Two won't listen and knocks Bad out. Once completed the planet begins to separate. The Sorceress tells He-Man that the only way to stop it is to return the Triad to their hiding places.
The palace is being struck by lightning and the masters are trying to keep it standing. One bolt of lightning causes a chunk of a building to fall down on Man-At-Arms and Teela, but before it can hit, Sy-Klone uses a whirlwind to send the chunk to fall elsewhere.
He-Man has returned the first of the three artifacts when Battle Cat is injured by a fallen tree. He-Man spots the dragon and hitches a ride to the remaining locations.
At the palace, the masters and He-Man are rebuilding the palace. Sy-Klone tells Roboto that the masters are his family and he is now happy. While at Snake Mountain, Two-Bad is eating and again break into a fight.
