Black Codex (2015) - 3/3
1) The false gods decide to release the full power of the titan souls, which have become twisted with madness in their captivity. Solas tries to stop them.
2) Unable to stop them, Solas instead creates a Veil between the physical world and the magical. He binds the Veil to the blood of the false gods, turning them into the locks on their own prison.
3) Early humans discover the ruins of the elven empire. Using knowledge scavenged from the ruins, Tevinter spreads across Thedas as a crude copy of the elven empire.
4) From their prison in the Veil, the spirits of the titans lure power-hungry Tevinter magisters into the Fade to release them. Instead of a city of gold, they find a Black City. The first Blight is released.
