Kind of a funny dream so I thought I’d share. Enter a couple in a wonderful relationship, you with the POV of the girl, feel like it is truly a match of soulmates. He is a magician, you are a simple lass, and you love each other even though you do not understand his quirks and the nature of his trade, and he indulges your little frivolities and girly interests. You have a head filled with thoughts of wedding planning, frou frou and fondant. After that it will be a quiet life, just the two of you, but you think you would be quite happy. Sated. If asked to describe it to a friend, you would say he makes you feel calm and keeps you sated.
One day, you overhear your partner “reporting” to a supervisor or headquarters with updates about their primary mission: they have been assigned to keep watch / guard an ancient eldritch creature for multiple lifetimes and centuries. They are weary but to lapse in their duty would upset a fragile balance and unleash unspeakable horrors… So the beast must always be kept satisfied. You feel sad for your beloved’s struggle, and admire their dedication, wanting to help their cause and ease their burden in any way. Then it dawns on you, as you listen further, that the nightmare creature is you. You feel yourself expanding in your skin…
