Sol gate
The name of a structure in The Expanse, entering with Abaddon's Gate, the third novel.
Sol gate is the name of a structure in The Expanse, and the name belongs to the series' middle and later volumes, entering the story with Abaddon's Gate, the third novel. The series does not begin with it: Leviathan Wakes opens on a Solar System that is entirely humanity's own, divided among Earth under the United Nations, an independent military Mars, and the working stations of the Belt, with tensions running through all three after the destruction of the ice hauler Canterbury. What the Sol gate is, how it comes to exist, and what it means for that divided system are exactly the questions Abaddon's Gate and the novels after it take up, and their answers are that story rather than background to it.
