A Rivenese woman and friend of Katran since they were children. Since Katran left, she had acquired a wound but she remained beautiful and full of warmth.

She joined the Moiety although she didn't believe the superstitions that Katran was the chosen one by god Atrus.

When Katran returned to Riven, Eti reunited with her. However although warm, Eti was indifferent, and nobody cared to ask how Katran had been all these years. She was hesitant to tell Katran about the Moiety beliefs that they consider Atrus a god. Usually she was friendly, but sometimes she felt awkward as if Katran was something superior. Whenever she mentioned her father and Enant, who were back in the surface, Eti's face was dimed.[1]
