Do you know why the Fair Folk take us? Why they are so intrigued by us?
Because we can die.
Our lives are defined by death. From our first breath, we rail against it, refusing to lay down and die. Our lives are a constant dance with it - some take up weapons and go forth to bring it, others tap-dance at its thresholds in the sky and deep waters, and still others strive against death itself. But in the end, we all go to death, whether it be calmly or in anger, and we weigh our life in tribute to ourselves. Death is our motive - we tell ourselves, when I am dead, what will be left of me? and craft wonders to answer that question. The wonders are left, even after we fade.
The Fair Folk cannot die. They do not feel the impetus to survive, to leave a legacy. They take us to taste our constant, exhilarating fear of death and joy of life, to sample our drives without meeting our ends.
And this, too, is why iron burns them. When a star dies, the last atoms produced before the nova are iron. Iron is the death of a star, and its kiss shows them the truth - that one day, even that which does not live or die will go out…
…but the starstuff will continue into the skies forever.
