LaTeX I'm trying to typeset a certain symbol in LaTeX

TL;DR Summary

I'm trying to typeset a black-filled crescent moon symbol in LaTeX. I want it to be exactly like \faMoonO, but filled in. I can't seem to find it in the list.

https://tug.ctan.org/info/symbols/comprehensive/symbols-a4.pdf

The symbol I've described isn't in this list. I've searched "crescent" and "moon", but to no avail. Will I have to go through the trouble of creating one myself using TikZ, or something?

Also, I need a horizontal border to insert above and/or below the words "THE END", which are centered vertically and horizontally in an otherwise blank page. If anyone knows of a package that already typesets an ending card, and allows also for extra decoration, I'd very much be glad to hear it.

Hi, if you use the TikZ library there is a command \moon{<day>} that takes the day of the lunar month as an argument and draws the corresponding lunar phase ...

There's no mention of such a macro in the official manual. If this is in reference to that StackExchange article, then that article explicitly mentions that that moon macro is a custom one. Moreover, it has that outer border that I don't want. I'll do some research on how to modify the code to create a black-filled crescent symbol.
