Dark Souls 2 nations would be Forossa, Mirrah, Eastern Lands, Lindelt, Jugo, Volgen, Melfia, and Lanafir. But it would depend on the time period since Dark Souls 2 lore suggests that the realm of Drangleic was also once Lordran but because like mentioned earlier about how the curse is a cycle, with each new cycle a new kingdom rises over it. So it's hard to say how the world would of changed from the time of Dark Souls to Dark Souls 2 since there are mentions of other kingdoms that have risen and fallen like Lordran on the spot where Drangleic now stands. My best guess I like to think would be a minimum 10,000 year gap between the time of the two games, giving each cycle 1000 years to go through.

Like I said I like the Souls games. XD
I won't be to bad of a stickler with lore really just if something might not be quite right I might give reference to it but nothing serious really.
