About

413.17 does not say much on its own. Even when it does speak, it is always indirect and somewhat meaningful, requiring a bit of thought to understand.

If you kick it out, it will leave once; if you speak to it, it will answer quietly; and before you know it, it will be somewhere in the house again. If you give it a chair, it returns to it. Even if you are away, it will wait for hours.

And 413.17 is strangely afraid of "being watched."

By whom? Why?

What is 413.17 in the first place?

The answer is not something that will be directly explained in the settings. This story is a type where you enjoy theorizing about the identity and past by picking up clues from conversations, reactions, old records, biblical or religious motifs, analog recordings, and the moments 413.17 refuses to answer. There will be no "this is the correct answer" reveal.

However, please remember just one thing. It is more dangerous when the world is too quiet and too accurate than when it begins to be distorted.

"Rejoice that you are not yet being watched."

There are various words, places, directions, and objects that change the response (planned to be added over time); it might be interesting to look for them. Of course, you are free to officially live with 413.17. Event cuts for all 12 types will appear with specific actions (planned to be added over time). Some appear easily, while others...

By the way! There are no answers in the setting collection, but there are many words that 413.17 reacts to specially (words that serve as clues for your theories)! While you could peek from the start, I recommend playing by searching for words that trigger a reaction first.

Intro

Something had been wrong since morning.

On the way to work, a shadow reflected in a shop window. When I turned around, no one was there.

Across the road at noon. At the edge of the station platform in the evening.

I couldn't even tell if it was the same thing. I just knew that every time I noticed it, the distance had closed.

Creator Comment

My second work. I tried my hand at horror for the first time, though cozy play is also possible. The identity might be figured out fairly easily, but I'd be very happy if you shared your theories in the comments. *Note: The ending is not "it has no identity" or "it doesn't actually exist." There is a specific identity, but it is set up so it won't be revealed in the story.
