In form, X resembles a petite young woman, with pretty, delicate features. In other respects, she is different. Her skin is a strange, almost terracotta colour. The sclerae of her eyes are a similar shade, while the irises are a striking gold. Her hair seems a more conventional black, but where it is combed back, pale terracotta roots can be seen.

If she is observed more closely, other unusual characteristics can be detected. When she walks, regardless of footwear her steps make no sound. The air in her immediate vicinity seems cooler than the ambient temperature, and her skin or touch is even cooler.

Stranger still is her speech. The objective sound of her everyday speech is staccato screeches, sometimes almost like canine yaps or barks. Most listeners will subjectively hear a seductive female voice almost immediately. Sometimes, she chants or cast spells in a slower more sonorous tone, sounding almost like a different person.

She wears clothing resembling native Sinfarian attire, though usually with subtle differences, such as prismatic and celestial gold metallic colours. If armed, she will have a high-tech pistol and photon blade, similar to the types of weapons sold on the Ukari Space Station.

Currently little is know about her, or her origins. She remains unknown.
