Lo scrittore principale di Mass Effect desiderava che il finale di ME3 si concentrasse sull’energia oscura, che stava per distruggere l’universo.
"The Reapers as a whole were 'nations' of people who had fused together in the most horrific way possible to help find a way to stop the spread of the Dark Energy. The real reason for the Human Reaper was supposed to be the Reapers saving throw because they had run out of time. Humanity in Mass Effect is supposedly unique because of its genetic diversity and represented the universe's best chance at stopping Dark Energy's spread" (Drew Karpyshyn).
Da qui, dalla forza devastante dell’energia oscura, tema appena sfiorato in ME2 e poi rapidamente abbandonato, trae lo spunto questa mia storia.
