I know its just headcanon but I've had this image in my mind for a while, one of a child miquella/malenia, a teenage/young adult radahn and godwyn all making an anime like vow of making the world a better place to eachother then it cutting to each of them, radahn rotted away not even sentient, malenia unconscious in her rotting tree, godwyn's mutated body, and miquella's decayed arm hanging out of the cacoon.
