510

510 is the only main character in the storyline. It harbours an inner self-hatred, choosing to refer to itself as "it" and not the normal pronouns of a normal human. Has a very deep understanding of martial arts - specifically ones involving a sword - and positioning during battles. Dislikes working with or even interacting with other people, and when it has to, it intentionally chooses to make a half-assed effort. It wants to find out the inner workings of the City of OZ.

## Physical description

### Summary (so far)

It is unsure about where 510 came from, but the only certain thing is that it came to the City of OZ via drop pod.

It is also unsure about how it got a wearable terminal on its wrist, as it only found out about this when it got a message from an "unknown\_user 252>" about a meetup, coordinates in the City, and a "new threat" to the City. After the meetup between unknown\_users was uncovered by an inside spy and crashed, it - like others in the group - fled deeper into the city and told itself not to trust anybody... any*thing*, and to find out the inner workings of the City.

It stumbled upon portal residue, AIs, demons, and even learned how to create a portal itself through a little gizmo on its watch/terminal device. After a few years of roaming about the City and trying to piece things together, the AI disconnects and cuts communication with it, and an unknown construct - later a "viral agent" - starts connecting with it. Intrigued by it, the viral agent decides to converse with it... for years.

43 years later, 510 wakes up to see a relatively new City of OZ and itself, as it has inherited the voice of this viral agent as part of its own. Questions would start flying in its head, causing it to get confused and lost off its initial goal. What doesn't help is the viral outbreak that occurs while it is trying to stay on point and figure out what OZ is running, and the former ends up causing a side effect of the first viral agent, leading to the formation of a second viral pathogen in its body. Having two voices in its mind would drive it insane and completely lead it off its path of finding out about OZ and on the path of finding out about the sources of these pathogens. It would later learn that the pathogens were not pathogens, but sentient beings with their own minds and wills.

One of those beings would end up manifesting its own physical form, Zelt, and it would go on and have another conversation with this Zelt for another 43 years.

It returns, 86 years removed, to a new City of OZ, but still with the same problems. With the will of Zelt transferred into its own consciousness, it learned about the source of these sentient wills and could finally turn back to finding out about the City of OZ.

On its mission to find out what runs behind the City of OZ, it chose to search for the one who started it all: unknown\_user252>. After asking him all the questions it had, as well as learning of the implant in its mind, it decided to find another source, as it had believed that unknown\_user252> did not have everything that it wanted to hear. Deciding that it be best to contact unknown\_user198>, who it vaguely remembered as a rogue Sentinel, and seeing what it was going through, it unwillingly "partnered" with two groups, one led by a mysterious Kaerai and another led by an even more mysterious Chiel and unknown\_user681>, to find it. After a video game-like maze, they stumbled across the rogue Sentinel's predicament, and after some questioning, it finally got what it had been searching all this time for.

During their little escapade, it decided to give Kaerai a small portion of the will that it had taken in, as the latter wanted to run some experiments. Such an attempt only created a second version of Kaerai, to which it could only chuckle at seeing their body doubles. After questioning unknown\_user198>, however, it decided to transfer all of the "viral agent's" will to this second Kaerai, telling her that its directive had finished, and that hers is to start.

After stepping out into OZ, it decided that maybe suicide was too good for it, so it would head back into its drop pod and lay dormant. It set goodnight\_sequence.exe to run, closed the hatch, and went to sleep. goodnight\_sequence.exe would end up returning a 4444 error...

### Trivia
