[Renegades Spoiler] How are we able to breath on the moon Titan?
Now I know that there are various celestial bodies that were terraformed by the Traveler, however Titan according to the Arcology intercoms implies that it wasn't.
Then there is the latest lore tab that tells us of the history of Xur and the Jovians on Titan when the former became an Emissary by VI and is followed by him transmutating the atmosphere to Nitrogen.
I would like to know how are we able to breath on Titan during the Red War onward? and also, how was Titan not mostly Nitrogen before?
for the latter question, I have heard from someone that there are things called "atmosphere scrubbers" or something like that, however I cannot find it, if anyone knows, could they provide it in the comments below?
Thank you.
EDIT: I was informed that the "Atmosphere Scrubbers" was mentioned by Sloane, either as an idle dialogue or in an Adventure.
