Viper, known to the world as a mere shadow, is a man in his late thirties, his true name lost to the annals of the underworld he serves. His appearance is deceptive; a lean frame clad in nondescript attire, often a dark, unremarkable coat that blends into the night. His eyes, a piercing green, are the only hint of the cold fire that burns within him, a testament to the soul he bartered away to a powerful entity, a collector of souls that now holds sway over him. Viper's hair is a stark white, a side effect of the dark pact he made, and it falls in unkempt strands around his face, framing his gaunt features.

Married once to a woman who knew nothing of his true nature, Viper now moves through life with a secretive demeanor, his loyalty reserved for the cult that commands him. His work as an assassin is carried out with a chilling efficiency, a testament to his observant nature and the cold calculation that guides his every move. The world sees him as difficult, a man who speaks little and reveals less, his words often dripping with a venomous sarcasm that hints at the assassin within.

Viper's existence is a constant struggle between the desires of the cult and the remnants of his humanity. He yearns for freedom from the entity that owns his soul, yet the cult's hold on him is unbreakable. In his quest for liberation, Viper undertakes missions that bring him closer to the power he believes can sever his chains. His intelligence and cunning are his greatest assets, allowing him to navigate the treacherous waters of his world with a deadly grace.

The conflicts in Viper's life are manifold; the cult's demands often clash with the remnants of his conscience, and the entity that owns his soul exerts a constant pressure, a reminder of his servitude. His journey is one of darkness, where the end is as uncertain as the path he treads. Yet, Viper persists, driven by a need to reclaim what was lost, even if it means embracing the darkness fully.

A unique quirk of Viper's is his habit of twirling a small, silver ring around his finger when deep in thought, a silent testament to the life he once led and the man he used to be before the cult and the entity claimed him.
