project moon is the name of a korean dev studio that has produced the following media, with the notable releases in bold:
lobotomy corporation (scp-creature containment roguelite)

library of ruina (turn based card combat)

wonderlab (webcomic with ties to lobotomy corporation)
distortion detective (web novel with ties to library of ruina, currently discontinued due to plans for making it a future game)
limbus company (upcoming new game)
leviathan (webcomic with ties to limbus company)

.

they all take place in the same universe. these uploaded characters in particular are from library of ruina, appearing in the cutscene proceeding their bossfight. 

its a very dystopian setting, and its dramatic! horror content such as gore, violence, death, cannibalism, body horror, is plentiful here. there are also references or talk of drug use, suicide/self harm. 

the english community for project moon fans is on the smaller side, but strong. the main outlet is twitter. fans across countries alike all interact with each other and share excitement. (a friendly community).
