During "Summertide", Lang has discovered a strange coincidence in the pattern of modifications occurring in Builder artifacts all over the local spiral arm, which leads her to visit Quake at the height of the summertide. She briefly forms an alliance with the cecropian, Atvar H'sial, before Atvar betrays her to partner with Louis Nenda. Lang is eventually rescued by Rebka and his team, who witness the discovery of the artifact Glister as it lifts from under the surface of Quake and heads toward the system's gas giant, Gargantua.
