You know what would be fun? If the warrior of darkness would really be derplander. He is supposed to be a stand in for the protagonist, but if you look closely, he never does anything in the cinematics that prove he isn't just some random adventurer. He was there at carteneu and was teleported to the future by Louisouix. He was in Ul'dah when the crysis broke out, but he was runnin alone in an area where we still had the Scions with us. When Nanamo drinks from her chalice we don't see who is sitting with her at the table.
He later crosses into Ishgard and gets attacked by what looks like Hraesvelgr on the bridge. Where he lives looks more like an inn room than Fortemps Manor. Cid flies him to the Dravanian Forelands, which never happened to the player. He also defends Ishgard from an attack while inside Ishgard.
His story most likely ran concurrently with the player's. Of course he doesn't have Hydaelin's blessing, and he fought and bled for nothing as the WoL killing Niddhog's consort made all the difference instead of his efforts. This could be enough to push him into the open arms of Elidibus.
