Death's Messengers is a German fairytale that is part of the Brothers Grimm collection. I like this story most for its similarities to Greek mythology. Death sends his siblings to warn a man that he is to die soon. Similar to Thanatos, these siblings include illness, the signs of ageing and sleep. What I love most about this story is the final words Death tells the man, he says something along the lines of: "Has not my brother Sleep reminded you every night of me? Did you not lie by night as if you were already dead?"
Honestly, the story has the framework of a BL and I hold no shame in saying if someone were to do it, I'd read it in a heartbeat - no hesitation.
