Villager from Ver Omesh who is featured in the Book of Origin. Markon's faith in the Ori was tested during a famine. He visited the prophet, Articus, and asked for permission to go feast on wild berries in a forest beyond the city.
Articus refused to grant him permission but drew a line in the sand, representing Markon's choice. Markon crossed this line and went to the forest. The berries, however, did not satisfy him, and he later returned to discover that the line had widened into a great chasm. Articus called to him, saying that it was not the line -- but Markon -- which had changed.
Markon prayed for forgiveness and took the first step across, and the hands of the Ori enveloped all those who welcomed him back.
Line in the Sand - In the hopeless attempt to encourage Vala to see the Ori as worthy of her allegiance, Tomin reads a passage in the Book of Origin regarding Markon. Later, Tomin and his Prior dispute the meaning of the same passage.
