Hidden Object: Ghost of King Black Magic

The mysterious story happened in one city. I was approached and asked for urgent measures to follow him. He could not really tell what happened, but what he saw - obviously frightened and caused much worry for the future well-being of the citizens and the city. When he turned to me, seeker magical mysteries and puzzles that do not take up regular studies. There is clearly involved magic spell or something like that. I should rather take up this matter and help the city.
