Before the advent of the thaumaturge in the West, the city of Ergonas had started to develop in the East, circa forty years or so after the first work initiated on Coepi Locus. Of the plentiful tribes which gradually amalgamated into a higher order society, the leader of the most prominent clan was Illcrue, son of Logosa. Spearheading the political foundation for a socially advanced civilization, Illcrue founded Ergonas after the principles laid forth in his father Logosa's work, Patronus yuî Keicīvilīis Logogeda. While no accurate synonym exists for Logogeda in the common tongue, the closest translation of this title may be accepted as Patterns of Social Reasoning.
Thus far in this history, the existence of Illcrue is historically certain; the following, however, is unjustified myth. Also note, though, that despite absence of physical evidence, no other explanation has been found to account for Xonil's origins.
In the synonymous year of 84 AAV in the West, Logosa died of the Swar'dlune skin epidemic. Illcrue, in despair, ordered the construction of a grand mausoleum at the center of the city's government center to honor his father's memory. In addition to the monumental strains implied by the unwaged civil work project, lack of his father's advice and wisdom led Illcrue, no more than a political figurehead sitting upon his father's works, into depression, and ushered the political and societal infrastructure of Ergonas into irreversible decay. Upon the completion of the mausoleum, Illcrue stood upon the high spire above his father's grave, and orated his last testament, now engraved in stone on the North side of the Shri Obelisk in Xonil:
Where Logosa has succeeded, I have failed;
Where He has directed, I have lost;
Where He has demonstrated, I have faltered;
Where He has suggested, I have altered;
And, ultimately, where His guidance would so point to utopia,
Variance in His path is no different than a degree's variance in the Hidden Forest.
Where the smallest detail in Logosa's principles lies unfollowed,
The destination is lost.
Upon these awing and confusing words, hoisted above the temple his father would have prohibited him from building, Illcrue incinerated himself alive by means of foreign sorcery; and Ergonas's decline was hastened.
This is the end of uncertainty in Xonil's origins: the rest is recorded, and thus quite certain. After Ergonas's decline into chaos, order began to rise from the anarchy. Two idealist clans both aimed for the recompilation of civilization, but they sought this through distinctly ambivalent processes. One group retained humanistic, Logosan thought. Realizing that his vision would be perfect if absolute trust in his methods was concrete, this faction adopted the label Ratiō. The other group was led by a revolutionist named Lufu, who cited the success of democratic, religious thought in the West.
After over eighty seven long years of war, Xonisvi, son of Radaisvi, led the Logosan army to victory, pushing Lufu's forces out of the modern day Xonic Peninsula. He established a city in his name, basing everything he could control off of the ideals laid forth in Patronus yuî Keicīvilīis Logogeda. His predecessors kept this vision, and maintained the most stable civilization in Avalor's history for over four millenia; a stable civilization, but a bland one.
It remains "happily stable", but grayish, to this day. Currently, there is a scare of foreign overextension of influence, and all creative thought has been "prohibited."
