A few months after the ink was dry on the Allobrogian alliance, Sotas I reached his majority and took up the reins of government. He began his reign by approaching the Gelids for a marriage alliance, as he was worried about the power of both the Megaklids and the Karsids, but he trusted neither of those mighty families.
A year later, in October 575 AUC, Sotas I married Phthia Gelid. This tied his new regime to the Gelids closely, and Sotas was well aware of that. Still, he didn’t let this cloud his judgment - when Theophrastos Megaklid and Antiphilos Gelid got into a fight a year after the marriage, Sotas sided with Theophrastos. Thousands of pages have been written on why, and they rarely agreed on anything. Theories range from the mundane - a fear of allowing the Gelids too much influence over him - to the fantastic - that Theophrastos and the Basileus were engaged in a torrid, secret love affair. What everybody agrees on is simple, though - the decision happened, and Sotas publicly justified it by mentioning Theophrastos’s good character.
Before that conflict, however, Sotas had appointed commanders for two legions that had been left leaderless during Karsid’s regency. He appointed a talented man from a minor family named Deimachos Timotheid as commander of the Greek Legion, and he appointed a Karsid named Karsis as commander of the Illyrian Legion based on the advice of his former regent. These appointments happened in May 575, and they were part of a general expansion of the Epirote legions and abolition of the former levy system.
However, the talented lesser noblemen never got to prove his talent. His greed prevented that, as he abused his office to embezzle money from his soldiers. Sotas found this out when the troops complained to him in March of 580, and he learned a lesson from this - never trust the lesser nobility with a military command. It was a lesson he would keep in mind until his death. The new commander of the Greek Legion was Demokleides Karsid.
In April 581, however, the main link between the Basileus and the Karsid family, Demophanes Karsid, the former regent, died. Sotas was told that he died due to working too hard, but the Basileus found this diagnosis foolish and always suspected conspiracy. He searched for further evidence of this conspiracy for years, but the only evidence that such a plot ever existed didn’t survive to the present day. We know that it existed, though, because ancient sources mention it - the Perfidiousness of the Nobility by Sotas I himself was allegedly the book that exposed it.
Still, Sotas was unable to change the past, and all the evidence in the world couldn’t bring back the dead. Cults that claimed to be able to allow the living to speak to the dead did exist, though, and Sotas sought them out. This was the beginning of his obsession with religion and supernatural and mystical truths. Legend has it that Sotas’s first meeting with the Cult of Tyche was to discuss with Demophanes about who should replace him, and the regent advised his king to appoint Arseas Karsid, his relative.
For a few months, Sotas studied his mystical texts in peace, but politics soon reared its ugly head. In August, Sotas’s own relative betrayed him. Nikeratos Apollonid, the Governor of Vocontia in Gaul, attempted to stir up a revolt among his people. He argued that he governed over Gauls, not Greeks, and the Greek King in Passaron should not be able to dictate his will.
He quickly adopted Gallic customs and grew a long beard in the Gallic style. He proclaimed himself Chief of the Vocontians, and a massive army gathered around him. When news finally reached Sotas of this development, he ordered all loyal Epirotes to kill the treasonous Nikeratos and destroy his army. Nikeratos Apollonid’s head reached Passaron on a pike in September, and the King is said to have smiled and proclaimed “thus always to traitors”.
