A neato thing about writing FFXIV fanfic is crossover events are built in - all those big plot Trials. OCs assemble!
I haven't written the Ultima Weapon fight but I've written the before and after from the perspectives of four different people, all of whom were there for it, and that's been a lot of fun to do as a writer.
How MMOs handle the player in story vs. the need for multiple players in certain content is fascinating - FFXIV is kinda weird about it but gives you plenty of room to build on the available interpretations. In my fic "Warrior of Light" is anyone with the echo, so the WoL is a WoL not the WoL - this means that four of them are gathered for the Ultima fight. It also means that my little fictional continuity has one WoL for ARR (Jacinthe) and one for Heavensward through Endwalker (and possibly Dawntrail) (Lauden). Writing the handoff was enormously rewarding.
So I've got a Light Party for future writing and space to expand that into a Full Party should I wish to do so. 🤔
