The Rune of the Closed Mouth

The Symbol of Ogion
The Closed Mouth
The letter Ogion sent to the Archmage was signed with the rune of the Closed Mouth. This symbolized silence and the hidden wisdom of darkness. It was a reminder that not all truth is spoken.
The Shadow in the Doorway
When Ged first entered the School, a shadow seemed to follow him. This was a foreshadowing of the light-darkness theme. The shadow was already part of him.
The Shadow as a Separate Entity

The Antagonist
The Evil Shadow
Ged saw the shadow as a purely evil entity that he had to destroy. This was a dualistic view: light vs. darkness. He fought it as an external enemy.
The Pursuit
For most of the story, Ged believed the shadow was a separate being. This conflict drove the plot, but it was based on a misunderstanding.
The Serret's Saying

The False Dichotomy
“Only shadow can fight shadow”
Serret told Ged that only darkness can defeat the dark. This was a temptation to use evil means. Ged rejected it, asserting that light defeats the dark.
The True Understanding
Ged's refusal was a step toward the correct understanding: light and dark are not opposed but complementary. He needed to integrate, not fight.
The Final Union

The Oneness
Light and Dark Meet
Ged and the shadow merged. The bright light of his staff and the darkness of the shadow became one. This was the resolution: light and darkness are two aspects of the same whole.
The Song of Éa
The epigraph of the book, “Only in silence the word, only in dark the light, only in dying life,” is fulfilled. Ged's experience embodies this dialectic. The theme is that opposites are not enemies but necessary complements.
