Ammut
(AKA Amam, Am-mit)
Ammut is female demon, she is found in The Book of the Dead,
She
plays an important role in the Hall of Maat.
We find Ammut during the judgement of the deceased,
when his
heart is weighied against the feather of Maat.
It was Ammut who would
devour the souls of those who's hearts proved heavier than Maat.
This was a
terrifying prospect for the ancient Egyptians.
It meant the end of existence.
They would never meet Osiris and live forever in the Fields of Peace.
