8. Andromeda's Timeline Runs Parallel With The Original Trilogy
A very cool timeline assembled by fan, NeroJoe, purports that across the entirety of the first three games, the events of Andromeda's story were also coming into being. According to the various leaks that have emerged regarding ME4's framework as humanity trying to find a new place to colonise and survive, it actually holds together perfectly well. The theory states that as far back as humanity's first discovery of Prothean tech on Mars, there has been existence of a mysterious entity known as 'the Ark'. Top minds from across the galaxy would then work on unlocking its potential in top secret, as the events of the trilogy play out. Right around the time of the Reaper invasion on Earth, Liara T'Soni passes on the same encryption keys used to decipher the Citadel's true purpose, to the previously-formed Ark Contingency (ARKCON), who have been getting nowhere with the artefact for around 30 years. Using the keys, scientists realise it's a gateway to the Andromeda galaxy, and make the necessary preparations to flee Earth through the Ark if the Reapers are successful in any severe capacity. No matter which ending your Shepard chose, Earth was left in one hell of a state of turmoil. The theory concludes that various flotilla ships with the necessary resources to colonise Andromeda leave through the Ark and destroy it on the other side to prevent being followed. These survivors of the Reaper War know nothing of how the battle actually ended, and continue forward, a new age dawning as the various species' within the groups begin to ruminate on what and who they left behind, before exploring what's ahead.
