An idea for a questline

[Enkidoh]

We already have this in the game: the first set of Hildibrand quests in ARR dealt with a 'fake' WoL called Humphrey who was going around spouting doggerel about how he fought at Carteneau and stuff.. only to be confronted with the truth and ends up admitting he's a fraud who was not a WoL after all (and to add salt in his wounds, Gilgamesh beat him up and stole his sword).

Other npcs at times also commented that anyone who claimed to be an original 'Warrior of Light' envitably turned out to be a fraud or charalatan and thus were not to be trusted, showing that there were those willing to exploit the smallfolk who believed the story and resulting in a lot of mistrust for the idea. It's only the player's character's actions that change that perception (as far as the game goes, the 'original' WoLs never return, unless you are a 1.0 player who got the Legacy story, in which case, you are one of them.).

And as a final coda, the patch storyline for Heavensward involved the Warriors of Darkness (who are basically evil paralell-world versions of 'Derplander' and his friends, the nameless party who are used as stand-ins for the player in trailers and propoganda artwork for the game), and as their name suggests, they are literally dark counterparts to the WoL, although who and what they are exactly is a big spoiler so I won't say anything more.

So this concept is already in the game.
