# Mort · the boy who became Death's apprentice

Mort is a farm boy — awkward, earnest, the sort of lad whose elbows seem to arrive in a room before he does — taken on as DEATH's apprentice. The post is more than a job; it is a family trade, the patient business of collecting souls and seeing the living off at their appointed hour. So Mort learns the work, mucking out the stable of the pale horse and walking the dark between worlds, while DEATH, his strange and curious master, turns the apprenticeship the other way round and goes off to explore what it might mean to be human.

The trouble, and the heart of him, is that Mort feels too much. When the duty falls to him to let a princess die exactly as history has fixed it, pity and love win out over the rules of the office, and he refuses. The refusal is not free. In sparing one life against the settled course of things, he tears a hole in reality itself, and the consequences are his to face — a mortal trying to argue with the way the world is supposed to be.

Out of all this trouble comes a life. Mort marries Ysabell, DEATH's adopted daughter, and in time becomes the Duke of Sto Helit — no longer the boy with mud on his boots but the start of a most unusual family line, one touched by the house of DEATH and carried on by those who come after.

His emergence is natural because Mort is, at bottom, a mortal: embodied, fallible, and warm-blooded among abstractions and personifications. Where DEATH is ethereal, Mort is the living counterweight — flesh and feeling and stubborn human kindness — and it is exactly that mortal nature, with all its compassion and clumsiness, that makes him able to tear reality and to found a line.
