Dear Professor McGonagall,

I am not sorry to say that Harry Potter will not be going to Hogwarts this year, nor will he ever. As the apocalypse has started, my Master is needed to do my duties for me while I am...indisposed. Add to the fact that Albus Dumbledore wishes to use him as some sacrifice for the so called "Great Good"...
You can see why we're not interested.

Sincerely,
Death
