"There is so very much to learn... You understand so little." —Xanvi, "In Somnis Veritas"
Xanvi is an extra-dimensional being, Oneirois-class reality manipulator, and the founder of the Dream Eaters.
Xanvi wears thick black robes with fur lining and a hood that hides his face. The proxy bodies that he uses to act outside of Statodnim appear identical to the other Dream Eaters, with bodies made of an ink-like substance and two heterochromatic eyes. The eyes on Xanvi's physical body were originally blue and gold, but in the years since the battle with Palvatar, they have become milky white and bloodshot.
Two piercings on the side of Xanvi's nose bridge hold up cracked glasses lenses. His flesh is a pallid grey with hints of purple.
In much the same way that a dream is simply an extension of the dreamer's mind, Xanvi sees himself as the center of reality itself. Xanvi considers the world around him to be an extension of his own being, and he feels a need to make sure that he is in control of every aspect of 'himself.'
Xanvi is incredibly well-read and intelligent, though he prefers endeavors of philosophical nature to the sciences. Due to his personal philosophy and beliefs, Xanvi cannot understand why an individual would commit to an action that doesn't directly benefit them.
Xanvi resided on a moon of Ermianu known as Sabin for a very long period. At some point, he seduced apprentices to serve him first with philosophy and then with the promise of power. Xanvi and his apprentices made contact with Euclid and other worlds, becoming very important figures in Munese tribal mythology. After killing the deity that ruled his home, Adonai, Xanvi personally spoke to a king known as Nzulk, offering the monarch the ability to become an apprentice if he created a device that would allow Xanvi to enter Euclid physically. The king declined, preferring his social status and position.
Eventually, the Powers discovered Xanvi's killing of the god Adonai, and attempted to stop him. A fight ensued, in which the Power Palvatar ultimately killed one of the apprentices known as Supay and numerous followers of Xanvi's ideology. In retaliation, Xanvi triggered an event which would result in the death of a large swath of Sabin's population and the destruction of most of his own physical body. Xanvi and his apprentices fled to a small desert planet. The seven survivors came to discover a device that would allow them again to enter Euclid, which they took full advantage of.
- Oneirois-Class Reality Manipulation - Xanvi has yet-unknown reality manipulation abilities, including teleportation, the ability to manipulate dreams and the ability to traverse them to travel between dimensions.
- Physical Projection - Xanvi can project a weakened physical form separate from his damaged body with an amorphous appearance. He uses this ability to disguise himself as John Fontaine and carry out the destruction of Remnant Rock.
- Functional Immortality - By connecting himself to the lives of his subordinates, Xanvi is able to survive fatal wounds and live well-beyond his body's limits. Despite this, he is unable to see the substance known as aether.
