To retrieve something important... (Open)

Saraki Blackwind was giving another step through the roof of that bulding, when he stoped to look around at the city. All seemed to be normal, yet not for him. He was on some kind of mission, but he was not sure if the appropiate name was "mission". While people lived their normal lives down there, he was on the search for the strange material called Orihalcon. This Orihalcon can be used in many things, such to unseal sealed doors, to giving great power to demons. That was his goal: To prevent demons to obtain it. He heard that one of this stones arrived to this city, and for some reason he thought that he was in the need of recovering it...

While jumping to another bulding, he noticed down in the streets some men walking around in a lonely street. Nothing to worry about... There was no need to care for such things.

Saraki went through many places, without clue of where to find this object....

How am I going to find such a little thing on a big city like this?
