Subcon's swamp, but sentient and chill. They've been around a long time.
Styx considers The Blessing to be their son of sorts, and used to give him advice and affirmation before he gradually got more and more closed off from everyone in Subcon. Only when he was visited by some odd but endearing people did they come out of dormancy. Now they look after the kids of The Blessing and The Fabled Fairy whenever they're near, and give advice with Moonie.
Porble. Goopy. Got some sticks and leaves. Styx has a welcoming presence about them. They're always attached to the swamp.
