This paper examines the critique of the oppressive patriarchy and the new visions on dragons, children, and women in Tehanu: The Last Book of Earthsea (1990) by Ursula K. Le Guin. With evolving feminist consciousness, Le Guin attempts to revise the male-oriented world of the previous Earthsea Cycle by writing Tehanu and presenting the dragon-girl Tehanu. In Tehanu, Le Guin describes the wrongdoing of "the bad fathers" mostly represented by the misogynous magical powers and seeks the ways to get over the phallogocentric universe. Therru, a girl who was raped and beaten and pushed into the fire supposedly by her father, resulting in losing one eye and one hand and falling into silence, is the vivid evidence for the brutality of patriarchy. While Tenar, who takes care of Therru and the magically deprived ex-archmage Ged, seems to take the traditional women`s role, she always asks who is a woman and what is her power. Le Guin investigates how women, children, and animals are assigned as the indiscernible, obscure others upon which patriarchical system erects itself phallologically, and of which men are afraid due to their otherness. That`s why Therru is revealed as Tehanu, the dragon-girl who called the savior-dragon Kalessin with the other eye and the other voice. As a child and a young woman and a dragon at the same time, Tehanu occupies "the emptiness which comes before power and has the potentiality" to stir up the patriarchical system. While (re)writing stories of Earthsea and the dragon people, who represent changes and otherness, Le Guin shows us how to revise our world and how to fly on "the other wind" of imagination.
