Oh, shiny! I really enjoyed this. You capture the feel of Sandman very well indeed, and the character pairings are inspired. Mycroft and Destiny are such a perfect fit. As she so often is, Death is my favorite. I like that you've scattered the meetings across time rather than trying to cram everything into the canon period.

I caught a couple of minor typos, both from the Death section:

-he is out of the door before he has even had a chance to breath. That final word should be breathe.
-right up until he has the arms of Rebecca Worthington’s killed yanked behind his back Killed should be killer.

All in all, I really enjoyed this piece!
