To have an object be infused with Origin isn't something completely new. Scientists have already discovered that far. However, what differentiates this map from other Origin-infused objects is the ancient nature of it.
That map is at least a few tens of thousands of years old and because of it, the Origin around it was as ancient as the map itself. Origin Users could easily identify of the Origin emanating from something. If it's newly added or very old, artificial or natural, etc.
This is where the problem lies. If something was infused with Origin, it would only stay in that state for at most a few days if not less, depending on how much Origin was infused into it. So, for this ancient map to have Origin stay on it for that long without vanishing, was abnormal.
That simple fact alone picked the curiosity of every person who had a deep knowledge about Origin within the room. However, none of them said a word. The tension in the room rose.
