This is the name that the Chinese gave to this mutagenic agent discovered on Ceres.

When it attaches itself to a host carrying the anomaly that can cause cystic fibrosis, Yú modifies its genetic expression, forcing an extraordinary evolution.


The Dawn probe was launched by NASA on September 27, 2007 and ended its service on November 1, 2018. Its goal was to approach and explore Vesta and Ceres, between Mars and Jupiter, in order to study and map the dwarf planets.


Dwarf planet located in the asteroid belt (between Mars and Jupiter). Recent observations have revealed that it has a spherical shape, unlike smaller bodies which have an irregular shape. Its surface is probably composed of a mixture of water ice and various mineral hydrates such as carbonates or clay. Ceres appears to have a rocky core and a mantle of ice. It could host an ocean of liquid water, making it an avenue for the search for extraterrestrial life. Ceres is surrounded by a thin atmosphere containing water vapor, which was confirmed on January 22, 2014 by the Herschel Observatory of the European Space Agency.

Dawn is now a satellite in orbit of Ceres.


Between 2000 and 2007, several undercover Ministry of State of China (MSS) agents participated in the construction and launch of the probe. Their work consisted of installing a spy system allowing the Chinese space agency (CNSA) to follow the progress of the craft in real time, and to receive the images and scientific data that it could collect. A system functioning as a dual command allowed several MSS agents working within the CNSA to take control of Dawn by simulating a stall of the craft and the end of transmissions for NASA.

This dropout occurred at the beginning of 2015.

The spy probe then transformed into an exploration probe. It took samples of ice and rock and then headed back towards Earth. In order not to be spotted by the various satellites and international monitoring programs, its arrival coincided with the launch of a new telecommunications satellite. The latter absorbed it and unfortunately returned to crash on earth. Chinese public statements have expressed deep disappointment over the failure to launch this new satellite. The recovered samples were immediately transmitted to the 10th office of the MSS which secretly took charge of the studies.


Mutagenic agent and consequences on genetics

Yú AGENT (魚)

Yú is a very aggressive mutagen. It takes its name from Chinese, meaning “fish”, because it was found in high concentration in the suspended ice and water vapor of the dwarf planet Ceres.

Yú acts like a virus, modifying the DNA of infected cells. Unlike the virus which “forces” cells to produce replicas of its DNA instead of their own DNA, the Yú agent combines with the cells’ DNA and modifies its expression. It adds an element to the AGCT nucleotide chain, the Xerosine (X) nucleotide.
If the agent is rejected by the body, death occurs within 48 to 72 hours if ingested or injected. The host dies within several days if inhaled.
If the mutation is successful, it acts immediately and will evolve throughout the life of the individual.

Only people carrying an abnormality on the CF allele causing cystic fibrosis can survive exposure to the Yú agent. Thus integrated, Yú develops faculties previously inaccessible to humankind. Today, it is estimated that one in 25% of the population carry this anomaly. However, the frequency of the condition varies according to geographic and ethnic origin: while Caucasian populations originating from Europe are largely affected, African and Asian populations rarely present this anomaly.


To date, more than 900 types of CF allele mutations have been discovered, some being specific to a single family screened.

Only people carrying the anomaly on the CF allele manage to integrate Xerosin into their genetic heritage without rejection and are able to survive exposure.

It provokes in them the development of visible or non-visible characteristics that are completely new to the human race, what we will more commonly call “abilities” or “powers”.

It is impossible to determine in advance the nature of the mutations as well as their aggressiveness on a fetus or a newborn. The first mutations occur more commonly at puberty. However, subjected to significant stress or situations of imminent danger, they can appear in younger cases.

We call “Prime Generation” the individuals who survived the natural exposure to Yú and whose mutations were devastating, even lethal. The life expectancy of these isolated cases is extremely short. Some did not reach adulthood, succumbing to horrific transformations. The luckiest reach fifty before retroactively experiencing the degeneration of their DNA.


A Native is said to be an individual who has been a victim of the natural exposure of Yú which will occur in October 2026. The Natives will survive it and will undergo violent mutations, although often fatal. They will become the said “Prime Generation”.

Candidates are young hosts selected by secret government organizations for generic studies and experiments.

As for Positives, their mutations are inherited from their parents, themselves Natives, Candidates or Positives.

Are there individuals immune to this ferocious mutagen? If so, would they make it possible to make a cure?

Waiting for the world to calm down and the surface to smooth out, they did everything to survive.

They are no longer afraid to be scared.
