User blog comment:Toby Aitchison/My Theory: Linking the Fire./@comment-16047389-20141216231502

Problems with this theory:

First off, linking, rekindling, and relighting are all synonomous terms, at least when referring to the First Flame. Gwyn is famous for linking the First Flame.

"By sacrificing himself to link the Fire, and commanding his children to shepherd the humans, Gwyn has blurred your past, to prevent the birth of the Dark Lord." - Darkstalker Kaathe

Note that he says link and not rekindle. And the Chosen Undead is said to link the First Flame.

"Your fate... is to succeed the Great Lord Gwyn. So that you may link the Fire, cast away the Dark, and undo the curse of the Undead." - Kingseeker Frampt

That's why the achievement for ending the game this way is called "To Link the Fire". The term "linking" did not originate in the second game. It came from the first game.

Second, this theory is entirely dependant on the idea that Drangleic and Lordran are in two seperate geographical locations. An idea that has become less and less believed since the release of Dark Souls 2, and its downloadable content.

Third, Dark Souls 2 has proven that the Curse of the Undead is not a perpetual event, but rather a reoccuring one. Dialouge with the NPC's reveals that kingdoms rise and fall with the disappation and reemergence of the Curse, and that it has been like this for longer than anyone remembers.

Fourth, the idea of two more Dark Souls games also depends on the idea that Miyazaki, the current president of FromSoftware and director of the original Dark Souls, would want to make more direct sequels. Miyazaki has shown that while he does in fact support spiritual sequels, he prefers to not make or be a part of direct sequels. This can be seen during the development of Dark Souls 2, where he had only an advisory position, and was hands off most of the time.
