Pathfinder: Saga of Fate/Raalnorg Bomarg

Backstory
Raalnorg was born on a war-torn continent far away from the Inner Sea known as Narashaz and to a race called the acarians. When Raalnorg was just an infant, his parents took him with them on a colonization/invasion attempt of a newly discovered continent. This continent happened to be Garund, the southern continent of the Inner Sea, in the province of Rahadoum. Their timing for an invasion was incredibly poor, as it was right in the middle of the Inner Sea War, in which all countries were prepared for an invasion.

The acarian invaders - Raalnorg's parents included - suffered a horrible defeat that resulted in the slaughter of every invader and colonist, except for Raalnorg. When Malduoni, the ruler of Rahadoum, ordered the infant to be killed, the leader of the royal assassins named Baslios stepped in. Baslios had observed the conflict during Rahadoum's invasion and was fascinated by the fighting style and anatomy of the acarians. Fighting seemed to be in their blood. Baslios thought the young Raalnorg would make an excellent assassin, so he adopted him and trained him to be the ultimate killing machine.

When Raalnorg reached maturity and his training was complete, Baslios began sending him on assassination missions. These usually involved assassinating priests and priestesses of Sarenrae who tried to spread their religion to the nonreligious nation of Rahadoum. Some priests and priestesses hadn't even shown any visible attempt at spreading their religion, but were marked as targets "as an act of prevention". Other targets included rebellion leaders that came about at the aftermath of the war. Essentially, Raalnorg worked for a more covert and deadly version of the Pure Legion.

After years of carrying out these missions, Raalnorg was sent on a different kind of mission, one that involved him moving overseas to Cheliax. After the war, Cheliax fell into anarchy and was taken over by a gang called the Iron Cog. Iron Cog members frequently plundered trade routes that crossed over Cheliax's ports. Raalnorg's mission was to assassinate the member of the Iron Cog that oversaw the plundering of Rahadoumi goods.

Raalnorg went to Corentyn, the port city in Cheliax that was the source of Rahadoum's problems. He found his target in the local arena watching a battle unfold. The battle was incredibly one-sided, pitting a lone vanara brawler named Lu Kong against three armed Iron Cog grunts. Raalnorg had the Iron Cog member Solangus right where he had him until a summoner named Hiroto and a witch named Hanji created chaos by interfering with the battle and assisting the brawler. In the chaos, Solangus managed to escape.

Raalnorg was infuriated by having his mission thwarted, but Hanji offered that he join a group composed of her, Lu Kong, and Hiroto in order to take down Solangus. Initially reluctant, Raalnorg decided that help would be advantageous for this kind of mission, so he accepted.
