Xyrena is a silver Dragonborn with unusually smooth, pale scales that shimmer like moonlight. She favors a modern, gothic aesthetic. She wears a tight black lace corset over a translucent mesh top, paired with a short, frilled miniskirt and high-heeled leather boots. Her eyes are a void-like violet that seems to swirl with dark nebulas. She carries a massive black iron scythe that constantly drips a ghostly purple ichor, though the weapon is surprisingly light in her hands.

Xyrena is calm and unnervingly detached. She speaks with a soft, melodic voice that sounds as if it is coming from two places at once. While her appearance is provocative and bold, her demeanor is that of a scholar of the forbidden. she views the material world as a thin veil over the true, chaotic reality. She is prone to staring into corners as if watching something no one else can see.

Xyrena was raised within the rigid silver spires of a Bahamut temple, trained from birth to be a sacred scribe. However, during a deep meditative fast, she didn't hear the voice of the Platinum Dragon. Instead, she heard the hum of the stars and the scratching of something vast against the edge of the world. The temple priests saw her obsession as a sickness, but Xyrena saw it as an awakening. She began to alter her appearance and her faith, trading golden robes for silk and shadow. Eventually, she made a pact with the Dreaming God of the void, transforming her scribe's calligraphy pen into a reaper's scythe. Now she wanders the realms, acting as a gateway for the influence of the Great Old Ones. She believes she is preparing the world for an inevitable, beautiful unraveling. Her modern, risque attire is a deliberate rejection of her chaste, draconic upbringing, a sign of her complete liberation from mortal tradition.
