The prompt: "write a formal complaint letter to your deepest, darkest fear."
You don't know me. You never will. I'm an Elemental you see. Immortal.
I know you have issues with my kind. You feel cheated. I understand, I think. You have a job to do, and my kind don't contribute to your cause.
Nevertheless, I'm writing to ask a favor of you.
I have chosen to take a human husband. I know you will come for him one day. I have accepted that.
However, we have had two children. Beautiful babies of mixed heritage. They are growing up so quickly. I cherish each new milestone. Yet, I tremble at every new step.
Because they are half mortal, half human. I fear you will try to take them one day.
You will come to call them away from me. It makes no difference how "old" they will be. They will still be my babies.
However, they are also half immortal. I believe that should be enough to remove them from whatever list it is you keep.
If you do come for them, be aware, I will be there. I will fight you with every ounce of my energy. As an Element of Air, that energy is rather formidable.
It would be much better for both of us if you simply bypass my children.
