So I just recently started playing, and from a narrative standpoint, I can't follow a thing- and I'm not THAT stupid. I don't think. I was following at first. Ghost wakes you up, takes you back to the city. You meet Zevala, and then he tells you to do a Vanguard Strike. Didn't know what that was, but followed his instructions. Then I was on some planet... I dunno which. Fighting guys I didn't know anything about, hunting some dude who made weapons for someone. I was mad at them for that? I guess? Then I had to do bounties in Strikes, so I joined another, and this time I was in some kinda haunted cave, fighting spooky bois. Now I'm getting sent to earth, which I thought the Tower was on? But I guess not? And I'm fighting the Fallen, who I at least know who they are from the first mission. What's going on? Am I doing things out of order? I got a warning at the start to do First Light before anything else, but I'm super confused.
