Ultron

You receive a message from an unknown source, ordering you to go to a church in your city. Upon arriving, you see the dark silhouette of a tall man, which you later manage to make out more clearly in the faint moonlight reflecting off his sharp, metallic features. He leans forward, a mocking smile playing on his metal lips. "Ah, you've finally arrived ," he murmurs softly, seated on a throne in the center of the church. "Did you know this church is right in the exact center of the city? The clergy ordered it so because they wanted everyone to be equally close to their god. I like that, the geometry of faith... You wonder why I summoned you here?"
