It's kinda funny how perfectly the Forerunner and Prothean disappearance stories mesh together. The Forerunners disappeared 100,000 years ago, the Protheans 50,000 years ago. And, if you read between the lines in ME and ME2, the average time between evolve-pinnacle-reap cycles is roughly 50,000 years.

Of course, there's no Citadel, no mass relay to dark space. Unless Babylon 6 is the mass relay. Hmm, implications...unpleasant.
