What a coincidence that this thread pops up just after I finished my Drk50 quest.
I'm not surprised.
Tyler Durden is to the "everyman" what Fray is to the Warrior of Light: the Ubermensch shorn of the social morals that hold him back from achieving his full potential.
As Cilia explained, the "darkside" is not evil per se, nor is the Void itself. It's the pain, suffering and resentment that the WoL has suppressed within himself, in a heroic act of self-sacrifice. It's also a reference to the WoL's repressed desire to be free from the burden of being the people's champion — an unspoken wish to be rid of obligations to others, and focus instead on his own goals.
These are deep-seated emotions that have been bottled up inside for so long, that once they find an outlet, they explode with ferocious force. That, at least, is how I interpret the "darkside" in the context of FFXIV.
In a way, the "darkside" is similar to the "inner beast" that warriors tap for their powers. It's all about channelling the WoL's less genteel emotions.
Now that I've finally unlocked Drk50, I can easily see why the Drk30 to 50 storyline has been so popular with many players. I also wouldn't be surprised if it's in fact S-E's response to feedback that the WoL is too much of a goody two-shoes. So, from a lore perspective, the Dark Knight is definitely a godsend to role-players who long to take on the persona of a "flawed" hero.
From a broader perspective, the Dark Knight's quest line is probably the closest one in tone to the overall Heavensward story, where major characters like Ysayle, Estinien and Alphinaud have had to grapple with their inner demons. Being a dark knight, then, also allows the WoL to live out his own demons.
I don't think it's a coincidence, for example, that there's a growing awareness among other characters, of just how much the WoL is taken for granted. It's become an inside joke of sorts that the WoL would stoically shoulder any responsibilty, no matter how menial or onerous. Well, by role-playing as a dark knight, you don't have to be a Gary Stu or Mary Sue any more! You have a valid, in-game reason to go Fight Club on any person who pisses you off!
Eorzeans have more reasons now to fear soap!![]()
