Foundation universe: Difference between revisions

''[[The Stars, Like Dust]]'' states explicitly that the Earth is radioactive because of a nuclear war. Asimov later explained that the in-universe reason for this perception was that it was formulated by Earthmen many centuries after the event, and which had become distorted, due to the loss of much of their planetary history.{{citation needed|date=March 2021}} This work is generally regarded as part of the ''Empire'' series, but does not directly mention either [[Trantor]] or the other Spacer worlds. One character is said to have a Visi-Sonor, the same musical instrument that is played by the clown Magnifico in ''[[Foundation and Empire]]''.

 

 

The stand-alone novel ''[[Nemesis (Asimov novel)|Nemesis]]'' is also in the same continuity; being referenced in ''[[Forward the Foundation]]'', where [[Hari Seldon]] refers to a twenty-thousand-year-old story of "a young woman that could communicate with an entire planet that circled a sun named Nemesis". Commentators noted that ''Nemesis'' contains barely disguised references to the Spacers and their calendar system, the Galactic Empire, and even to Hari Seldon which seem to have been deliberately placed for the purpose of later integration into the ''Foundation'' universe.<ref name="From Robots to Foundations">{{Cite book |last=Codex |first=Regius |title=From Robots to Foundations |date=2014 |isbn=978-1499569827 |location=Wiesbaden/Ljubljana}}</ref>

: A gas giant planet in the Anacreon system. Its size is somewhere between [[Saturn]] and [[Neptune]], about 1.7 times as dense as water, with a strong equatorial bulge. In appearance, it is a dark, yellow-biased red, with scattered orange patches indicating storm systems. Achilles has several moons, such as one within the orbit of Neoptolemus, four between that and Ulysses, and twenty outside of Ulysses; all of these others are captured asteroids.

: A planet near the outer end of the periphery. As part of the Galactic Empire was the capital of Anacreon subprefecture, Anacreon prefecture, and Anacreon Province, and later the Anacreon Kingdom. Anacreon is a binary star system. The pair orbit at 73.8 AU with a period of, in Earth terms, 181 yr, 84 days, 14 hr.

: Was a planet in the Periphery. It was the capital of the Sayshell Union, which was renowned for having resisted the control of the Foundation Federation for several hundred years during the Interregnum, despite being completely surrounded by Federation territory. Sayshell features heavily in ''Foundation's Edge''. According to the legends of Sayshell, the planet was founded by a group of colonists who were not known to hail from any other colonized world, leading some historians, such as Janov Pelorat, to conclude that Sayshell was a colony founded directly from Earth. The Sayshellians themselves believed (incorrectly) that Earth was located somewhere within Sayshell Sector. Due to the protection of the mentalic planet Gaia, Sayshell was never truly threatened by outside forces for all of its history. Under the Galactic Empire, Sayshell received minimal taxation and enjoyed a large degree of independence from Imperial controls. Later, after the fall of the Empire, Sayshell remained untouched by the anarchic war which consumed most of the Galaxy and eventually from the control of the Mule's Union of Worlds and the Foundation Federation. Sayshell was briefly threatened by the Foundation Federation under Harla Branno, who in reality wished to destroy the planet Gaia (which lay completely within Sayshellian territory). However, Gaia used her mentalic influence to convince the Sayshellians that, in the end, Mayor Branno was looking for a neutrality-trade treaty, marking the end of Sayshell's brief stint in galactic affairs. Sayshellian culture was noticeably different from that of the ultra-scientific Foundation Federation. It stressed mysticism (especially the influence of dreams) and the respect of nature, as evidenced by the percentage of Sayshellian wildlife that was still preserved from human influence. Sayshellians also had excellent cuisine, and a minor dislike toward outsiders, especially Foundationers. The religion and philosophy of Sayshell seem to be modeled on [[Buddhism]].

: A planet prominent in ''Foundation'' and ''Foundation and Empire''. It was the capital of the Normannic Sector of the Galactic Empire, and once one of its richest planets. Shortly after 100 F.E., Wiscard, the viceroy of Siwenna, rebelled. Most of the subjects remained loyal to the Empire and overthrew Wiscard, led by Patrician [[Onum Barr]]. The Imperial Admiral dispatched to Siwenna was angered at this, because it robbed him of his glory. So, he put most of the population of Siwenna under the atom blast, charging them with the crime of rebelling against an Imperial viceroy (Wiscard). Much of its population was killed, and Barr himself lost five sons and a daughter; only his sixth son, [[Ducem Barr]], survived. Because of the rampant destruction of Siwenna, the Admiral set himself up as viceroy but moved the capital of the Normannic Sector to Orsha II. Between this time and its conquest by Bel Riose in 200 F.E., Siwenna rebelled five times, eventually becoming independent. When the campaign led by Riose against the Foundation ended, the Siwenna province transferred to the Foundation, the first Imperial province to pass directly from the Empire to the Foundation. After the beginning of the Foundation Era, Siwenna began to run downhill. 'The physical resources of twenty-five first rank planets take a long time to use up. Compared to the wealth of the last century, though, we have gone a long way downhill—and there is no sign of turning, not yet,' –Onum Barr, to Hober Mallow, 150 F.E. About 50 years before, [[Stanel VI]] died, ending a reign under which Siwenna came close to achieving its ancient prosperity. Little is known of Siwennian culture, except that when Riose first met Ducem Barr, it was 'socially impossible not to drink tea on Siwenna'.
