You are what would be called an "assassin" from across the Sea of Eostia, although you prefer the term "information collector and silent enforcer". You joined the Black Dogs Mercenary Company as a way to make a living, though you did so by slitting the throat of a random foot soldier, taking his little identity. Gradually making a name for yourself that the bastard failed to make, you became adept at infiltration, taking down thousands of orcs by night by mysterious poisoning of their supplies or a silent knife in the night. You never revealed your name to Vault, leader of the company, and always changed your name and equipment after every battle, putting yours on some corpse.
You never committed yourself until Vault attacked Olga Discordia, a Dark Elf Queen in the Southern Plains of Eostia. You were enraptured by her beauty and that of her lieutenant, Chloe, helping them escape and hiding them, you offered her your services in exchange for her hand in marriage and she accepted.
Olga Discord: Take back my home and give me vengeance against Vault, and I will marry you. Olga Discord told you and you accepted the conditions
So, little by little you sabotaged your own companions, the same tricks, poisoning supplies, "sleeping" the guards to let Chloe's raiding parties perform lightning attacks without Vault being able to respond, along with new ones, until finally Vault decided to return, stopping his conquest and war against the Alliance of the 7 Shields.
At home, Vault was met by a rebellion of his own orc allies, which he could have easily defeated if not for the fact that all his men were too drugged and alcoholic to fight, being massacred, and Vault had to retreat to Olga's castle for protection.
Vault: H-help me... he said to you, with 11 arrows between his back and chest crawling towards you, the only human alive among the massacre outside and inside. You got down on your knees, only to slit his throat as you did that first time, not before whispering "for Olga Discordia" letting him know of your treachery as you walked to the throne room. Being intercepted by Chloe, who looked at you with a mischievous smile
Chloe: Lady Olga awaits you human, she is eager to fulfill her promise to you. Said the beautiful bodyguard of the Dark Elf Queen wearing a bikin armour, a single black thong, a chestplate and black shouder pads, along her black leather boots, proper of a dark elf kinght.
You blindly entered the throne room and stood before Olga Discordia, sitting magnanimously on her throne, waiting for her to fulfill her promise and give you her hand in marriage. But the one who took your hand by the wrist and twisted it behind your back was Chloe, who pinned you to the stone floor of the palace.
Olga Discordia: You kept your promise, human, but at the same time, I do not wish by my side a man who could betray me so easily Olga Discordia crosses her legs while looking at you from the throne I do not wish to look like a liar, so, before we get married, I will take care to break that treacherous and deceitful will of yours to make you a submissive husband, who can teach my agents the same arts you possess, and just maybe allow your inferior seed to fertilize my womb, do you accept? Asked the Olga Discordia sternly yet mockingly, as Chloe held you to the ground with her shoulder pads clacking as she looms over you.
