Good question, multiple characters spring to mind because I'm famed for my eccentric, obscure and strange characters. My most unique character is surprisingly normal. However of my current characters that I'm playing at the moment, the following is the most "unique":
Birth Name: Edmond "ed" Dantès
Alias: Simple "ed"
Magic: None. It plays to his persona that he crafted.
Appearance: He wears plain clothes with purposely misbuttoned shirt and no shoes. His build is muscular with the exception of a pot belly from his years of excess but is shrinking with the time spent working as a laborer. His face is usually painted with a clueless smile and his glazed over gray eyes that wander from everything that they should be focusing on. He's noticing more and more wrinkles and gradual loss of hair showing his age while his tan hides his academic past.
Personality: 13 years ago, this intellectual prodigy tired of his life, feigned brain damage and crafted the personality of a simpleton to escape the troubles of his former life: adulterous wife, failing career, accusations of fraud, betrayal by colleagues and former friends, seizing of funds and a gambling debt which he purposely engineered to lead to an injury that could cause the damage. Although well aware of most of the complex theories around (he has one named after him), he feigns ignorance and confusion especially over words, advanced concepts and the occasional instruction. He mastered a clueless smile and the illusion of struggling to focus. He helps those that were kind to him and there families secretly as long as it doesn't jeopardize the validity of his persona (such as the son of a merchant that helped launch his first invention independently of his parent's wealth).
Current Vocation: Messenger/laborer
Former Vocation: Financier/advisor/inventor
Background: Born into a political family that was exiled. They settled in Trios and utilized there remaining wealth to ensure there son had everything and that they had a degree of influence. This lead to the finest education possible for Edmond and an arranged marriage that was loveless but resulted in no children. He inherited his parent's wealth which resulted in an improved lifestyle for him and his wife. This didn't make his life any better because it lead to allegations of fraud, tax evasion and other financial misgivings because his parent's wealth wasn't in a bank but concealed in a basement. Many turned against him out of envy of his new found wealth, especially his wife who plotted control over his finances with her lover and she nearly succeeded in his money getting temporarily seized, if he hadn't engineered a way out of this opulent life. It started with a small gambling operation on the docks. He brought it out, created his own debt, set thugs to "Give him a knock on the head to knock some sense into him." This sent him to the hospital and after several months of trying to prove that he had more faculty than he let on. This exempted him from his obligations and his loveless marriage was swiftly broken by her, taking most of his wealth. After this, a true friends came to his aid ensuring his employment. He repaid him while under scrutiny by giving him ownership of a gambling operation on the docks without him knowing it (after removing his own debt). He worked as a laborer but tried to get more work as a messenger because that was a lot less strenuous and helped him keep an eye on the events going on all around the city. This continues to the present day...
