I've gone through the main story twice and I'm now going through my third run through and I've started to notice something.
Keepers of the Moon barely exist. I was already aware that there is VERY little lore on them shared in game, but as I've moved through the game I've realized that it's not just a question of lore but presence.
Just about every single Miqo'te I have run across is a Seeker of the Sun. Young or old, civilian or soldier and I'm not just talking about Miqo'te with any relevance to the plot. Practically everyone from random Miqo'te walking about to shop keepers are Seekers.
On the one hand, I'm aware that the lore places most of their population in Gridania, there's no good explanation as to why Seekers came to be found all over the place and Keepers in just this one small section of the entire planet. What's even more confusing is that this great disparity even exists in Shadowbringers where such a consideration wouldn't even factor in.
So where are they? Am I missing something here? Am I mistaken in how rare it is to see a Keeper in the greater world? This would honestly be less frustrating if there was any lore what so ever explaining their absence beyond just saying that most resettled in the Black Shroud. Compared to the Seekers, it really feels like they barely exist between both game presence and lore. It's frustrating and I really hope there's something I've been missing.
