Loppurets: Their purpose

[Alenore]

This was my interpretation as well.

Though I have a crazy theory that the Lops are Amaurotines that somehow managed to survive and since degenerated and/or evolved in to space bunnies.

Someone please replace Emet-Selch model by a Lopporit on the after-Hades cutscenes.

Maybe they could surprise us last second and have them playable? Hrothgar was also a last second surprise if I recall.

[Archchancellor]

So in lore some people in Eorzea must have some idea of there existence, for this t have been made.

I am just going to say I called it.

I am just going to say I called it.

For what it's worth, the description of the minion itself in the minion guide:

While it is whispered that this cheerful vagrant is the sole surviving member of a tribe hailing from none other than the moon, most see Namingway for who he is─a queer fellow with a penchant for giving all he meets absurd nicknames then jotting them down in his mysterious journal.

Not completely wrong, but it is worth saying that the Namingway minion (at least, last anyone checked; I'm not online right now so I can't see if they updated it) implies he was the actual guy, rather than a wind-up minion. But other than that, the description actually mostly lines up if you read that we're looking at a few-degrees-removed, lost-through-retelling version of what happened.
