The Triarchy

The Triarchy is a mercantile and military alliance of three superpowers of the Pagan Sea, created in 1431 in response to the emergence of the Corsair Queen Ana Yazi, to protect their common interest of securing trade and asserting dominance over the Pagan Sea. The alliance was struck between the magnates of the Valonian League, under Princess Luchella Aryaan, the Free City of Qadimea, represented by the influential slave trader Kamara Nazul, and the Sultanate of Osmany, ruled by Osman Yazi. 
== Origin ==
After having established herself in the city of Zis, Ana Yazi, the youngest daughter of the late Sultana Elyria of Chorene, launched multiple campaigns and raids in the Pagan Sea, harassing the lands along the coast and capturing islands in the Astentine Shallows, blocking her siblings from leaving the gulf while imposing high tolls on all safe passage through the Shallows. Her league of pirates sailed as far as the Valonian League, where many local pirates, including the Pirate Lord Vargo Sixfins joined her cause. In the spring of 1431, she captured Kraken Isle, creating a garrison able to shield her seat at Zis, which sowed much fear within the courts of Metina and Valona, worried she would not stop there. 
In April of 1431, the magnates of the Valonian League sent one of their own, Prince Castellan Godfrey, on an expedition to the Ayyubid Emirate. Here, he met with Kamara Nazul in the city of Qadimea to discuss a potential alliance. Although complacent with paying Ana Yazi's tolls, since the Shallows had indeed been made much safer by her presence, the price of these tolls only increased until Kamara and other great merchants could ignore the Corsair Queen no longer. A deal was struck between the League and Kamara Nazul, who would support the League with ships and slave soldiers to defend their coasts and merchant's vessels, giving them the measures to fight back against Ana Yazi. In return, the League agreed to legalizing the slave trade within their lands, a practice which had been outlawed for 90 years, and much longer in the surrounding nations of Magnia. When far to the north, Sultan Osman Yazi, stuck in a ceasefire with his sister Mustafaya, caught wind of this recent development, he launched his great fleet, throwing the Chorenese Coast into a state of panic. But the Sultan did not seek to gain land in Chorene just yet. Instead, he sailed to Hotar, where he razed the only city in the region, taking any survivors as prisoners, and sailed to Qadimea by way of the Free Cities. Wishing to break his young sister's iron grip on the islands, he met with Kamara Nazul and offered his Hotari prisoners as a gift. 
On May 6th, the three leaders forged the "eternal alliance of the Triarchy", with each gaining the title of Prince or Princess Admiral in addition to their other titles. Each state in the Triarchy was to remain entirely autonomous, but for the fields of trade and warfare. The alliance recognized a common interest in these fields, as well as the overwhelming dominance the three together could assert over the Pagan Sea. 
== War for the Astentine Shallows ==
Upon the formation of the Triarchy, Princess Admiral Kamara Nazul immediately launched an invasion of the Astentine Shallows with the support of Osman Yazi's royal fleet. The League of Valona was however unable to join in the assault, busy securing their own coast, while King Robert of Magiore threatened war with the League to stop the re-establishment of the slave trade.
