The Advent of humanoid grimm

Nobody knows when for sure that humanoid Grims first appeared some thought that it might be due to grim and humans or fuanus having a child others thought that they might have been people taken by the Grimm and transformed the final theory that people had was that they were simply an evolved form of grimm that mimicked the form of humans and faunus ( since most people in remnant do not know about Salem myself or you guys whoever wants to write can add your own ideas how she's involved) . They had both male and female humanoid Grims some of these Grimms used weapons which looked like they were black material and white bone others simply had bodies that were made for fighting nobody actually knows what happens when you're caught by one of these things but the three popular theories are you're ( fucked literally) taken for breeding purposes or simply to be eaten by them or you're simply transformed into them somehow

( honestly this is a spontaneous thing that I came up with after seeing a picture of a humanoid grim having sex with Rwby characters you guys can do whatever you want with this this is fully up to you. you can either create a really long story out of it or simply short to medium stories just for singular events so go ahead and have fun with it if you want)( you can choose whichever origin for the humanoid Grims you want)
