No edge used for me to spread.

To dance through the forest with song and grace,
Ever to become a tasty snack that once had a face.

Second Part:

Regarded as the primary, the protag, or the first,
Now as the crown of a beast, who hungers and thirsts.

Even some people, are considered to have me,
To clarify that which is most important you see.
