Project E was the code name for Divinity Original Sin. The executable name (EoCApp.exe) refers to the original working title, Eyes of a Child, but the plot had to be revised as the game kept growing in scope (initially there were going to be 2 main characters, with very different personalities and backstories, with one of the early revisions of the plot involving a child who could paint the future, and the Black Ring seeking to capture the child to exploit that ability).
