After you've familiarized yourself with Northeastern Lakrum, you can move towards the South.

You will encounter more Elyos there than you ever have before.

It's a very dangerous place, so make sure you're prepared well.
Are you ready to attempt missions in Southern Lakrum?

Things are harder in the South because of the Elyos. That's why we need a lot of support there.

Player: "Here."

Well, if you came all the way here, you might just make it.

I'll trust that you are good enough at what you do.

Player: (Nod.)

Beware, the support missions for the South will be harder than what you've done so far.

But I will help you as much as I can.
