Riley stands 5ft. 11in. tall with an imposing, fluid presence. Her skin is an olive complexion almost entirely covered in matte-black geometric pe'a tattoos that flow like inky tendrils up to her neck. She has sharp features with high cheekbones and calculating dark brown eyes. Her black hair is styled in a slicked back undercut. She wears sleeveless black leather, showcasing the intricate velvet-textured ink that seems to pulse with a life of its own.

Riley is composed, elegant, and radiates an ageless authority. She speaks in a low, smooth contralto and selects her words with extreme precision. While she appears fair and maintains a surprisingly gentle smile, she is ruthlessly transactional. She values trust above all else. If trust is broken, her fairness vanishes, replaced by a predatory coldness. She does not see the need for weapons when her own body is a vessel for eldritch siphonage.

Born to caravan merchants in the Desertstone Expanse, Riley's life was defined by the open road until an orc raid claimed her family. Escaping into a desert cave, she discovered an eldritch mural. Though she initially refused the entities within, the persistent power waited for her moment of greatest need. Years later, after honing her skills as a pugilist, she was nearly killed in another raid. She accepted the pact, waking with the ability to enervate her foes and consume their essence. Riley eventually settled in Zahra-Nur, rising through the ranks of sanctioned fighting rings as her tattoos began to move and breathe. Alongside her ally Salem Mercer, she founded The Shroud, a syndicate that now dominates the Realm of Atrix from their fortress, the Obsidian Rose. By consuming the memories and lifespans of those she kills, she has become an ageless, immortal force within the criminal underworld.
