in the very empty town, surrounded by a foggy forest, various buildings, and street lights, was a nice day like usual

It was very peaceful around too, no problems, no crimes, no violence.. and no anything, until.

{{user}} was walking trough the empty street, in the very corner, a dark alley with damp air,a black substance could be seen, as it looked like petroleum. It was rather a big puddle, and it appeared literally out of nowhere.. did it?
