Arks as Relays...possible?
I can't remember where I saw it but somebody on one of the myriads of ME fan sites out there suggested a plot twist where the Arks doubled as Mass Effect relays. According to the ME wiki, it was built by the initiative using an experimental drive core for the long voyage. What if they used Prothean technology unearthed by the Ryders to construct it? And after the events of Andromeda, now they can settle on different planets in the cluster, leaving the Arks to be reconstructed into Mass Relays.
The Pathfinder still has more to do and is eager to explore, as seen at the end of the game. Ryder and crew can continue exploring outside of the cluster, placing a footprint on new worlds (while discovering new species and the outlier Angaran settlements mentioned in the game). Take an ark once things are safe and then place them on different points in various systems to get across parts of the galaxy easily. Naturally, this would take a long while, but perhaps it could add some fuel for the next game, all the while dealing with the Kett incident and maybe some shaky diplomacy relations with the Angara. Who knows, maybe the Benefactor already knew the Arks were capable of this and assigned some engineers to make sure there was a smooth transition. Plus, with the chance to still access Ezo resources, you can definitely apply this to the reconstruction.
Thoughts?
