I have done this to myself not once but twice during Yuletide.
a friend requested narrator/Jolene (yes, the song). and my assigned recipient one year wanted Ulla/[unpronounceable by human tongues] sea spirit from the Grishaverse fairy tale collection
me over here like "if I had a nickel for every time I had to write fic of a nameless character, I'd have 2 nickels. which is not a lot, but it's weird that it's happened twice."
So while thinking about that joke and an actual thing to do with it, I realized part of the solution: All of Counters have four letter names. So copy something from Phantasy Star (original Quadrology).
Like, that's less of a joke than it sounds. There's an implied naming convention for the Squad, so it applying to the Commander to is actually sorta elegant.
