You know not what you have unleashed by asking me this.
I don't have any characters that are the Warrior of Light/Hydaelyn's Champion, per se. But I do have characters who are party members of the Warrior of Light. They're Scions who have the Echo, and they're part of a shared canon with some friends where certain details are different from person to person. It's pretty loose.
Coda Belltower is a Viera bard who left his original home in the Golmore Jungle for Eorzea shortly after the calamity. He's a wanderer at heart, and he often pens songs related to his travels and the things he's seen. His skill with a bow in combat is brutal, and he uses his voice to rouse the spirits of his companions. He has a big soft spot for kids, and he sometimes plays songs at the orphanage in the Firmament. He's romancing Aymeric. They're very soft together.
Hirsklorh Glazankasyn is a Lominsan Roegadyn fisherman who uses his skills with an axe to find mercenary work on sailing vessels. He uses the Gil to continue funding his fishing habit. Genuinely, as a character, his main job is Fisher and Warrior is his side thing. He's very laid back and gentle, but he will throw himself into a fray at a moment's notice to protect those he cares about. He's also very popular with the gay men of Limsa Lominsa. He has stories.
There's also another character I'm working on that's completely unrelated to the MSQ. His name is Beaumont Cartier and he's an Ishgardian author of political fiction. He's frustrated that he can't fully explore the themes he wants to explore without being deemed a heretic though, so he also publishes crazy controversial dragon erotica under the penname of Reverie Legrand where he can be as anti-war as he wants. Complete tonal shift from the others, I know.
