I made this because I was making telegram stickers for myself and needed to make a mask that properly fit the skull shape of the Titanian race. This is totally inspired by the ones from Nausicaa of the Valley of the Wind, though I made some modifications. Instead of herbs, activated charcoal is used because Kanil industry is a lot more developed than the failing biosphere. They don't make breathing sounds the way human masks do, because they use tesla valves instead of butterfly or check valves.
