So I just finished the mission where you go to eden prime and find that last surviving prothean.
However, in some of the things the prothean says, he speaks like he knows the asari and krogan races.
My question is, how does he know? My understanding was that the protheans were alive, fought the reapers, lost, whole universe is dead, and is reset, then asari, krogan, humans, salarians etc. are born.
