Mass Effect: The First War by
ProfFartBurger reviews
The Prothean Ruins weren't. They contained little more than mentionings of an Alien Society; as a result, humanity develops on a completely different path than what was intended, and when first contact is made not with the Turians, but a desperate, destitute race viewed as beggars and thieves, how will this dying race change Humanity? And how will Humanity change the Galaxy? *A/U!*
