Under the warmth of the Eternian sun, He-Man and Teela were enjoying a rare moment of tranquillity. Their walk had taken them far from the royal palace. "This is a pleasant day," remarked Teela. "I wish we did not have to return so soon. Such occasions are too few in number." "I agree," replied He-Man. "However, our duties prevent us from staying away longer." Suddenly He-Man placed his hand to his head. "What is it?" asked Teela, although she already knew the answer to her question. "A mental summons from the Sorceress," said He-Man. "I must head for Castle Grayskull at once."
