This character and general design belongs to SAD-ist on Youtube. This is from two animations on her channel, which are linked down below. I also have made the other character featured in the animations into a Minecraft skin too, which will also be linked below. If you clicked on here because this character has the same name as the Narrator from the Stanley Parable, or for other Stanley Parable related reasons, this is because SAD-ist was heavily inspired by it.
