Zaherux is a planet from the Mass Effect Universe. Its nitrogen-argon atmosphere is being blasted away by the solar wind of the blue giant Grissom. Its surface consists of "seas" of loose silica dust, some kilometers deep, which periodically swirl into global sandstorms. Many unmanned probes to Zaherux have been lost over the years. Though investigation has attributed all to mechanical failure or computational error, a popular extranet meme insists the entire planet is composed of dormant nanotechnology, created millennia ago by a race even more advanced than the Protheans.
