The butler and servant assigned to Shevek during his stay on Urras. At first Shevek is baffled by Efor’s role and laments the class divisions in Urrasti society that have put Efor in a place of servitude. After expressing an interest in Efor’s life, and the lives of the lower classes, Shevek wins Efor’s trust, and the two become companionable. When Shevek fears that the Ioti will steal his intellectual property, he seeks to escape the University where he has been staying—and it is Efor who helps guide him to the socialist enclave where he will presumably be safe.
