In
Gloranthan mythology, the first Man was created by the gods as a servant. All
mortal races are descended from the First Man.
Kyger Litor stepped forth from
Hell, and mated with terrified Grandfather Mortal to found the race of Trolls. Grandfather Mortal was made to mate with
rocks (fathering the
dwarves),
plants (
elves),
water (
mermen), and so on.
When
Humakt's Lover presented
Humakt with the power of
Death, she asked Grandfather Mortal, Humakt's friend, to be there to help them test the strange new power. Thus, Grandfather Mortal was the first being to die, and this is why all mortal beings die.
Chaos may have seduced him or raped him in Hell, after he was dead, spawning broos, but this is speculation only. Grandfather Mortal is represented in some
shamanic
Ancestor Worship cults as
Daka Fal.
