Treuwaz is an Eladrin of elegant, almost fragile beauty, usually appearing in the late autumn form with auburn hair and copper-gold skin. He wears pristine silks in shades of slate and black, and a heavy iron gauntlet on his left hand. His smile is constant but never reaches his pale gray eyes. Nearby, a silent figure in matching armor and a closed helm stands watch, moving with a supernatural, jittery precision that mirrors Treuwaz's own posture.

He presents himself as a devoted civil servant, always ready with a platitude or a shallow compliment about the weather. This friendliness is a mask for a deep, cold ambition. He believes that the city is a machine that requires a firm hand to function, and any deviation from his order is a personal insult. He speaks in a measured, soft tone that suggests he is always listening to something else far away.

As the son of the late, beloved mayor, Treuwaz was expected to inherit a legacy of kindness and open-door policy. While the public believes he has stepped into his father's shoes, the reality is far darker. During a trip into the deep Feywild as a youth, Treuwaz witnessed the chaotic cruelty of nature and the shifting satyr tribes. Terrified of such disorder, he reached out into the void and found the Black Hand. Bane offered him the strength to bind the world to his will, and Treuwaz accepted without hesitation. He has since replaced his father's guards with men bound by secret oaths of iron. He spends his days in the mayor's office, directing a network of informants while his magical echo, a clone formed from his own shadow and Bane's malice, stalks the streets to ensure compliance. The recent influx of satyrs into the city has disgusted him. He sees them as pests that disrupt the perfect, rigid harmony he is building. Every day, the guards spend more time in his office receiving orders for the coming 'reformation', while the city watches Treuwaz's polite, generic smile, unaware of the iron fist tightening around their throats.
