Now this is probably Fairy Tail's version of the "Black Plague" or "Hinamizawa Syndrome." If it was like Joker Venom, the people in this village would easily die from inhaling it. Anyhow, if Tempesta is still alive, I wonder if his true form is that of a ghost or an eldritch abomination since he said he has to sacrifice "one of his lives."
