Seeing as Shadowbringers involves the Warrior of Light becoming the Warrior of Darkness, I was kind of curious how that'd go over once we got back from the First Shard. Hypothetically we could keep throwing around darkness and save the day, but I feel like it's more plausible we'll wind up wielding light and darkness to become an agent of balance: the Warrior of Dawn.
The name was from Final Fantasy V for the group that fought Exdeath before Bartz's group and we are already in a group called The Scions of the Seventh Dawn, which the title would gel well with. Besides, the WoL always winds up being good at everything to a ridiculous degree, so it probably wouldn't be unreasonable that they wind up gaining some kind of special title that distinguishes them among their peers.
I suppose it's a little silly to think about where the story will go after 5.0 before 5.0 even comes out, but I just wanted to share my little idea and see if that seemed like a reasonable guess with the way the story is playing out.
