The Sirian Experiments
Doris Lessing
 The Sirian Empire, centred in the Sirius star system, has advanced technology that made their citizens effectively immortal (barring accidents) and sophisticated machines that did almost everything for them. But this technology came at a price: many Sirians became afflicted with "the existentials", a debilitating malady that left them feeling worthless and with no reason to exist. To overcome this problem and give its people "something to do", Sirius embarked on a conquest of space and colonised many planets. But they also encroached on territory of the superior Canopean Empire that led to a costly war, which Canopus won. As a gesture of reconciliation, Canopus returned all the captured Sirian territory and invited Sirius to jointly colonise a new and promising planet called Rohanda (an allegorical Earth). Canopus took the northern continents and gave Sirius the southern continents. Ambien II, one of the Five who run the Sirian Colonial Service and also govern the Sirian Empire, represents Sirius on Rohanda. She sets in motion a series of bio-sociological and genetic experiments where large numbers of primitive indigenous people from Sirian colonised planets are space-lifted to Rohanda and adapted there for work elsewhere in the Empire. In the north, Canopus nurtures Rohanda's bourgeoning humanoids and accelerates their evolution. They also put a Lock on the planet that links it to the harmony and strength of the Canopean Empire. Canopus keeps Ambien II updated with reports of all their work, but she is suspicious of Sirius's former enemy, seeing them as a competitor rather than a partner, and is unable to correctly interpret them. Then an unforeseen "cosmic re-alignment" breaks the Lock and Shammat of the malicious Puttiora Empire begins exploiting the situation by corrupting Rohanda's Natives. Canopus, seeing Rohanda decline, renames the planet Shikasta (the stricken). Sirius, unconcerned about Canopus's troubles in the north, continue to refer to the planet as Rohanda. In an attempt to foster better relations with Sirius, Klorathy, a senior Canopean Colonial administrator, invites Ambien II to observe events in their territory. Ambien II, eager to learn more about Canopus, agrees. As Rohanda evolves and civilisations come and go, Ambien II and Klorathy meet several times to watch Rohanda's degeneration. Canopus does what it can to help communities, but with Shammat's evil and a broken Lock, they make little progress. From time to time Klorathy requests Ambien II's help and while working on the planet, she meets Nasar, another Canopean official. She also encounters Tafta, the Shammat commander on Rohanda, and at one point nearly succumbs to his corruption. Ambien II eventually abandons the Sirian Experiments in the south when they are overrun by Shammat. The Five want her to abandon Rohanda altogether, but she has become too attached to the planet and is warming to Canopus and seeing the error of her (and Sirius's) ways. The Five question her ties to their former enemy, but when she tries to explain herself, they do not hear what she is saying, just as she initially could not hear what Canopus was saying. The Five then send her to Planet 13 on "corrective exile" to write a report on what has happened (this book). When she later releases the report, the Five issues a statement denying the authenticity of Ambien II's work.
