In "Summertide", Nenda comes to the Opal/Quake planetary system because his slave, Kalik, has performed calculations similar to Lang's and discovered the same anomaly that points to the planet Quake. Nenda partners with Atvar H'sial after Atvar abandons Lang on the surface of Quake so that they can work together to reap the benefits of witnessing a major Builder event together. In the end, they are "kidnapped" by the new artifact Glister as it moved away from Quake to orbit the gas giant Gargantua.
