Jesser

"For such a hateful flesh, it sure seems to love my presence."

Description
Hidden in the depths of a cave lies a family of beings. One is a massive and sedentary amalgamation of flesh and bones, one is a harbinger of wrath and disease, and the rest are the harbinger's puppets. The humanoid is covered in many gashes and bits of red, tender biomass indicating some sort of anomalous infection. Bits of bone are exposed from the wounds which have shown to not be of his own biology. Likely caused by the partner of his symbiotic relationship, a massive SCP-610 entity burrowed under the surface of an archipelago.

Origin
Birthed from parents of anomalous origin, he is able to live comfortably alongside typically hostile entities with a few exceptions. His initial experience with anomalies aside from his parents was a massive SCP-610 outbreak back on earth. Fortunately for him, the entities which he encountered welcomed him with open arms. The parents were not so lucky, as their first instinct was to attack any manifestation of 610. They were eventually consumed right before Jesser's very eyes; this would have no significant effect on his mental health as he was incapable of complex emotion at his young age.

Breach Incident
After a massive outbreak of 610 on Earth, MilkCo and its associates took notice of a particular man who wasn't exactly being mauled by amorphous blobs of flesh like everyone else. It was immediately evident that some anomalous interference was happening here. Captors swooped in and snagged the man, taking him back to an earth facility. Due to the outbreak, it was decided amongst his captors that he'd be taken to another planet's moon for safer observation and potential testing.

A transport vessel containing multiple anomalies had just recently landed in a remote location on a continent known as Aurora, located on UR15-A-C-H. The captured man and some samples of SCP-610 were taken to a testing facility, along with samples of the T9 virus. A man known as Dr. Jekyll had ordered hasty testing on the prisoner who'd been brought along, but not after concocting yet another prototype supervirus.

Jekyll had managed to combine a sample of SCP-610 and T9-5, which would be dubbed T9-5.5. Upon close observation, it was noted that the two instances fused very well together, thriving now as one disease. Jekyll, being a slight bit of a coward, ordered a group of his cronies to inject this new virus into the subject who's name was revealed to be Jesser.

An audio log was found sometime after the events described within it, it reads out as follows.

''00:00 - Subject has been fully injected with a sample of 5.5. No immediate results shown.''

00:30 - Subject's skin has formed splotchy rashes all over, significant distress has been observed.

''00:35 - Subject suddenly began to writhe and scream in pain, sores have begun to open up all over his skin. It seems as though a strange gurgling noise is being emitted form some of these lesions...''

''01:33 - Almost an hour after the sores began to open up, subject has finally calmed down. Sores have opened much wider now, leaking blood and some sticky, black substance.''

''02:04 - Sudden changes in subject's behavior have been observed. He is extremely hostile now, much more than before. Also to be noted, the subject is threatening to eat the flesh from our bones.''

''05:00 - The sun has just risen and we are currently beginning to prepare for a containment breach, subject's test room has been locked down and secured to the best of our abilities. It's only me and my partner left in here, and we have already prepared to give our lives for science.''

''05:03 - Subject has breached his restraints and is currently attacking the ballistic glass window as I am writing this, he has increased in size and weight and is showing remarkable strength. (A very loud cracking noise can be heard amidst loud banging.) Is he- HOLY SHIT HE'S BROKEN THE GLASS-''

05:04 - (Loud shrieking and growling can be heard in the mix of agonized screams and flesh tearing, it is assumed that the entity had breached containment at this time and consumed the scientists during this event.)

''05:05 - (A grisly, chilling voice can be heard over the mic.) Someone wasn't careful, and now you've started something you can NEVER finish. (The audio cuts here, followed by loud static.)''

Post-breach
After having claimed the 2 scientists who had injected him with the same virus that had taken them over, Jesser managed to organize a multiple-anomaly breach in the facility. On his warpath, he managed to infect several other personnel, leading them away from the facility. Months of trudging through a seemingly infinite icy wasteland led them to a coastline, where a somehow still operational boat was anchored. Jesser, still being human at the core, gathered his new family and set sail to an archipelago in the Northern Auroran Ocean. Soon after arriving, a deep cave was spotted on the surface. Jesser decided this would be the perfect place to manifest an instance of SCP-610-A, a biomass-type entity which would be a perfect home for the rest of the infected.
