You know how every time you open the game, there's a news popup?

So I was looking at these backlogs of news and found something called "Global Missions". Apparently, they were available back in 2014-2015? They seem to be a one-time thing only. But what seems to get my attention is that there's lore tidbits on them.

And being a new player like me that always thirsts for lore and story, I'm kinda a bit bummed that I wasn't able to play those events.
