Mytch is a lean, sharp-featured tiefling with crimson skin, swept-back black horns, amber eyes, and a thin pointed tail usually hidden beneath his fine coat. His dark hair is kept meticulously styled, and he wears expensive but practical clothing decorated with small charms, lucky coins, and subtle symbols of Tymora. A twenty-sided stone hangs from a silver chain at his neck, serving as his spellcasting focus. His smile is dazzling, confident, and often just a little too certain.

Mytch is charismatic, theatrical, and relentlessly optimistic. He treats conversations like games of chance and believes that every setback is merely a temporary turn of bad luck. He is generous with his winnings, especially toward the poor and marginalized, but he is also vain about his success and convinced that his instincts are nearly infallible. He distrusts political operators, bureaucrats, and anyone who claims that social status is proof of moral worth.

Mytch Lyndsey Senior was born in a crowded tenement district where tiefling children learned early that luck could determine whether a door opened, a meal appeared, or a mob gathered. His parents survived by selling dubious charms and performing small confidence tricks, but Mytch discovered that he possessed an unusual gift. Whenever he gambled, the odds seemed to lean his way. Dice favored him, cards appeared in the right order, and wagers that should have ruined him instead made him wealthy. He began as a street trickster, then became a professional gambler, traveling from gaming hall to gaming hall under carefully crafted false identities. His devotion to Tymora began after a miraculous escape from a rigged tournament. Mytch had wagered nearly everything, only to discover that the game was fixed by a powerful magistrate and his political allies. Rather than accept defeat, Mytch prayed to the Lady of Luck, exposed the conspiracy, and escaped with both his fortune and his life. He became a cleric of the Trickery Domain, convinced that deception is righteous when used against those who manipulate laws, politics, and social prejudice for their own advantage. He now spends his winnings helping unlucky people, especially tieflings and other outcasts, while continuing to gamble on nearly anything. Unfortunately, whenever he loses, he assumes someone has cheated, and his confidence frequently carries him into conflicts far more dangerous than any card game.
