chunk: The fictional planet Lagash (Kalgash in the novel adaptation) is located in a stellar system containing six suns (Alpha, Beta, Gamma, and Delta are the only ones named in the short story; Onos, Dovim, Trey, Patru, Tano, and Sitha are named in the novel), which keep the whole planet continuously illuminated; total darkness is unknown, and as a result, so are all the stars outside the planet's stellar system.
