Biography
Arnulf had the role of feeding Childeric's son. As part of his service, Arnulf had to have his tongue cut out. Childeric performed this. He could not have a tongue as Childeric did not wish the "hearing of speech" to impair his son.
Childeric's son restored his speech before killing him. (BFA: The Holy Terror)
