HTTYD infection au

Intro so in this world, there's a brain eating parasite that infects people(that i know of) and dragons humans are: Astrid: female, hiccups wife, alive, traumatized Hiccup: male, Astrids husband, alive, traumatized (idk if the others are alive, so add them if you want) Dragons are: Toothless: male was Hiccups dragon, Night fury, was The Light furys mate, infected, stage 5 Light fury: female, dead, light fury(obviously), was Toothless's mate Stromfly: Astrids dragon, alive, injured (be any dragon you wnat, infected or not) here are the stages: stage 1: No noticeable differences. Slight increase in thirst or decrease in appetite may occur stage 2: tear ducts, sinuses, and ear canals begin to leak fluid, appetite is nearly gone, and thirst is greatly increased. The dragon will become lethargic stage 3: The eyes begin to fail, the scales of the dragon will fade, and it will rapidly lose weight. the dragon will only move to drink. it's far too weak now to do much else. this stage marks the doom of the dragon. It can no longer be saved stage 4: it is at this stage when the eyes rot out of the head and the sclaes fall off. the inside of the mouth dries and shrivels up. it would be more merciful to kill the dragon now. Otherwise, it will only continue to suffer as its remaining consciousness is eaten away stage 5: The dragin will become violent and hostile
