Amusement park invitation
In the city, there is an area that seems to be impossible to access, its amusement park. Any tries to approach it end with failure as the area around it seems to be warped in such a way that instead of getting closer, one starts to make circles around it. And for some time, the park was just a landmark, something one can only look at. That was until a pass through the sewers was found that led to the amusement park (and with it the zoo, botanic park, and normal park around and between them). The explorers that got there encountered spirits and biomes not seen anywhere else. But whether it was that the spirits didn't like the intrusion inside the pass or in the area of the amusement park, whenever someone enters the pass now, it starts to fill with Leech spirits, leading to Skirmishes of Amusement park pass, making going through it way harder.
A few months after the first expedition to the Amusement park area, mysterious fliers started showing up around the city. Announcements of the opening of the park and the zoo appear on the walls near settlements, on people's doorsteps, and in their bags and pockets. They are colorful and covered with many images, some looking like normal amusement park attractions, while others look alien, weird, and bizarre.
Woah, how intriguing! Quite the mystery...very fascinating. I wonder if any other passages into the amusement park may be found. Also the question of 'do you miss the childlike joy in the world that abandoned you' is too funny XD
