[Prompt] Introduce Your World In 50 Words

I've seen a lot of these "tell me about your world" prompts on the subreddit, but they often result in people either writing massive walls of text or a single short sentence that is incredibly vague.

So instead I want to try something different. Introduce your world using exactly 50 words, not more, not less. Not sure if that's a good number, I guess I'll find out.
