in Twisting Ruin, there are the Brights, they're hostile to all but themselves and dust bunnies (neutral). However ever since The Bright Infection, most undefined, Johns, and Smiling Domain himself got infected and are half Brights. They're still hostile to non-brights however. Netherite John King left this universe and FS Domain is with the Brights for Smiling Domain's sake, so you're on your own. Also the Brights and Half Brights are immune to the cold and water due to Diamond John King and Ice John King on their side, but they can't swim well
