A new trailer released yesterday showcased the so-called Golden Worlds of the Andromeda galaxy -- the planets that have the highest chance of being habitable. But one small line may have just revealed if quarians are actually making an appearance in Andromeda.
The video, in case you missed it, goes through descriptions of seven potentially life-sustaining worlds, though one in particular should be of interest: Habitat 5. The voiceover says:
"For our turian and quarian colonists, Habitat 5 appears to be a perfect home for dextro-protein life."
So... quarians confirmed? It's the first mention we've had of the race that most notably gave us Tali in the trilogy. Of course this one mention doesn't mean that the quarians will actually appear in a large role in the game, or at all, but it's a pretty promising sign.
