The details as to where this individual came from and what had set him down on this path were lost to time. While many would seek to cover up their past, to hide the minute details or the grand story beats of their tale; Sinais merely had none. He was no one of interest or consequence. Even his name, untraditional meant he had no ties, no links to the common heritage of the Xaela. Like so many walking this star; he sought to make a life for himself but while many would attempt to align themselves to the path of honesty and good will… he did not. A void, nothingness. He felt no morality, no regret or apprehension to do or undo what needed to be done to feed the ever growing hunger of ambition. Emotions were lost to him like dust in the wind. Feeling no fulfilment in the arms of another or being content with the company of friends. All he had was the hunger; the desire to control and maintain all he could. It was through his close knit mercenary band did his pockets become lined with gil and thus his true hunger begin; that of wealth. But living among cut throats, thieves and vagabonds means trust was in short supply and in time his growing tenacity had become a threat, one that was to be snuffed out.
Scars of the Past, Heritage for The Future
While the inevitable betrayal left him scarred: he had survived. His horn, his cheek all becoming disfigured against a wicked blow which now left his visage ravaged by envy. Sinais fled taking all of the fortunes amassed with him after a feigned death. This left his former allies desperate, manic in their loss of their means of gluttony and in turn they devoured one another like starving dogs. Sinais however had used his means to jumpstart what he felt was the future; To amass a network of control built on the despair of those whom had come to be indebted to him. Being so disconnected from the feelings that drove man, he was able to take a step back and truly understand them, and thus, did he create the Serpent's Den: A gambling den built into the bowels of Ul'dah.
One would partake of the gambits in its dark halls with the goal of earning their fortune but the games were never in the favor of the common man. The odds border on impossible but the reward is vast. However through these nigh impossible odds did debts grow and so too did Sinais' sphere of influence. Land, residences, mercantile control, even one's life or those of their loved ones all came into his sharp grasp. The crumb of potential for one to go from counting pennies to amassing millions was far too advantageous for one to pass up and thus they pressed on to attempt to be the one to turn the odds in their favor. So many thinking they were the ones, they alone could “win”. So many with the same thought only stood to add another to the ledger and grow Sinais' control.
