Where can I find more information on the Gloaming Court/Gloaming Fey?

Recently I have stumbled upon some lore that refers to the "Maiden of the Moon", who is apparently one of the "Gloaming Court". There seems to be very little information out there on the web generally, and this is not something I’ve encountered in 5e (the only edition that I really know much about) beyond the occasional reference (e.g. one of the Circle of Dreams druid’s class features briefly mentions it in passing).

I assume that 4e will most likely have the most information given that the Feywild was introduced in 4e, but if there are any references to the Gloaming Fey/Court in earlier editions (or if I’ve overlooking something in 5e), then any lore from any edition is welcome.

Just to be clear, my focus is on the Gloaming Fey/Court generally, not necessarily the Maiden of the Moon specifically (although I’m also interested to know more about her as well as part of the general information about the Gloaming Fey/Court).

What I’m looking for is lore, not gameplay or mechanics; I’m hoping that an answer will say "there’s a big chuck of information in <insert book name here>, and also in these Dragon magazines <insert various magazine numbers here>", ideally with page numbers or at least section headings. I’m not necessarily expecting large quotes trying to compile all of that information here.
