Oisin I, King of Cahir

**Oisin O'Breathnach Roza**, also known as **Oisin the Bastard**, **Oisin the Conqueror**, **The Rose Prince**, and regally as **Oisin I** was the first King of Cahir and the man who led the Oisinite Conquest of Cahir. Having gone into exile from his homeland following the First Usurper's War, Oisin would go on to carve out a large domain for himself which would introduce the Rozanian culture and faith to the Island for the first time. It is as a result of the Oisinite Conquest that Cahir is the Island it is today.

## Early Life

Oisin O'Breathnach Roza (Born Oisin Buckfort) was born the bastard son of William Buckfort, at the time the Count of Sarissa, and a tavern worker in Karosgrad named Cara O'Breathnach. For most of his young life, Oisin spent his time helping his Mother work in the tavern and playing amateur wargames with other children in Karosgrad. When Oisin became a teenager, his Mother gathered enough money to send Oisin to public schooling in order to teach the boy how to read and write. Oisin, unknowing of his noble heritage, lived a relatively calm and uneventful life until he entered his young adulthood.

## Adulthood

When Oisin became an adult, he was sought out by his father William Buckfort. In their first meeting, William apologized for not raising the young Oisin himself and that he wished to bring Oisin with him to fiefdom of Sarissa to make up for the lost time. Encouraged by his mother Cara, Oisin packed his belongings and moved south to the island of Sarissa to join his Father. Oisin grew amazed at Sarissa's cleanliness and how his Father William had, according to William himself, turned the town from a small farming village into a proper settlement with stone walls.

Oisin, who had always taken an interest in military affairs, joined the Sarissan guard and quickly became the Captain of the Guard when the young Buckfort showed leadership potential to his Father on multiple occasions. As Captain, Oisin put down a small anti-religious rebellion in the countryside of Sarissa utilizing artillery and makeshift barricades. Having impressed his Father, William continued to encourage Oisin's growth in a military lifestyle and allowed him to conduct more recruitment and training campaigns.

It is around this time in his young adulthood that Oisin would meet a dark elf woman by the name of Jadwiga of Sarissa. Jadwiga and Oisin took a liking to each other and, despite Jadwiga being one of Oisin's subordinates, entered a relationship with each other. Their unofficial union brought about the birth of Oisin's bastard half-elf son, Szymon Buckfort, who Oisin would grow to have a mixed relationship with as the years passed. Eventually, Oisin sought to become a more pious person and broke off his relationship with Jadwiga due to Oisin's religion forbidding the relationship between an Elf and a Human. Oisin's attempt to become more pious would also strain his relationship with Szymon, and the two would grow more strained as the years went on despite both still harboring love for one another.

Eventually, the Sarissans under William were forced to leave their homeland of Sarissa and traveled to the midlands of their home continent to establish the Kingdom of Rozania with William Buckfort as King. Oisin, being one of William's more elder children (Out of William's alleged 10+ children), attempted to request that his Father make him heir over his elder brother who had not been seen in Sarissa for some time. William refused, citing that Oisin was still a bastard, and stated he would not inherit Rozania. Oisin swallowed his pride and accepted his Father's decision, but his pride had taken a serious hit due to the refusal taking place in a public court. Some argue that this is where the wedge between Oisin and William began, as their relationship began to take a downward spiral following the establishment of Rozania.

Some time during the construction of Rozania's capital, Roza, Oisin had met a human woman by the name of Diona Fleurgrass, his Father's former mistress (Unbeknownst to Diona, who had lost her previous memories in an accident). The two bonded over their love of scholarly matters, and the pair began a relationship. This time, Oisin proposed to Diona and the two scheduled a wedding. William remained silent regarding Oisin and Diona's courtship until the very day of Oisin and Diona's wedding. Just hours before the wedding was to begin, William declared to Oisin that he would not permit Oisin to marry Diona and slandered Diona with various curse words. This enraged Oisin, who struck his Father. William grew enraged by his Son's actions and disowned and banished Oisin from Rozania.

## Oisin's Rebellion/The First Usurper's War

Oisin, enraged by his Father's actions, raised his Banner in rebellion and formed the House of Roza in defiance of his Father and took the surname Roza instead of Buckfort. Oisin fled to the independent Principality of Sedan, who granted the Prince shelter and offered to pick up Oisin's cause as their own. Oisin accepted, and the war began in full when soldiers under William's command attacked the Principality of Sedan's capital of Louisville, sparking the First Battle of Louisville. The Sedanian soldiers, who had been battle tested in other wars, made short work of the relatively inexperienced Rozanian troops who Oisin had formerly led as their captain. The loyalists would attempt to attack Louisville a second time in the Second Battle of Louisville, but again would be defeated by the Sedanians and Oisinite Rozanians.

The War would reach its climax in the Sacking of Róża, in which the Sedanian-Oisinite force would scale the walls of Rozania's capital and sack the city while massacring the civilian population. Oisin, unable to stop the massacre of Civilians, was devastated by what had happened to those he considered his own people. While the Sedanians had taken the city and placed William's crown upon Oisin's head, Oisin would not remain in the city for long. Civil unrest against Oisinite rule was strong, and Oisin knew if he remained in the city he would face a struggle by his Father's loyalists to retake it. Therefore, he took his Oisinite soldiers and stowed away from their Homeland and sailed into uncharted waters to find their fate, which ultimately ended the First Usurper's War.
