A Christmas After-Tale: the Shoemaker's Curse

I, Isa Lauris Schumacher, am from a long line of...you guessed it, shoemakers. Over two-hundred years ago, my ancestors in Germany, began Schumacher Shoemaking in a little shop. A little shop that almost didn't make it. Until it did.
Everyone knows the tale of the Elves and the Shoemaker, right? Wrong. You don't even know half of it. What you don't know, ever since the Schumachers' accepted the Elves' gifts during that time, a curse was placed upon them. A curse that's currently killing my dad, like it did his dad, and his dad's dad before him, all the way back to the first. They all died before their thirty-seventh Christmas. Well, my dad's thirty-seventh Christmas is on its way...
Not only the men of my family is doomed, but the Other-World where the Elves, Fae, and Othercreatures live is in peril too. If that world is to perish, the human one won't be far behind. Only the blood of a Schumacher can stop it. At least, that's what I'm told by my family's Helping Elf.
