Once there was a promising young technomancer who abandoned all of his principles and collected everyone's data. He told them it was safe with him, and in time they believed him.
Over time the technomancer realized he had amassed so much information that he became mightier than even the leaders of the world, but his greed and desire for wealth kept him from noticing.
He began to sell his influence to these leaders and got them hooked on his data.
They used it solve crimes, and they used it protect the endangered, and they used it to detect who would likely do crime, and they used it to keep the people divided, and they used it to topple one another's nations.
All the while making the no longer young technomancer even more powerful and wealthy.
The prophecy says that the Technomancer will try to destroy those who oppose him. But the agents of the wires will bring him to his knees by rebuilding what was lost.
