Grendel

The horrible throbbing pain was unspeakable.

It pounded.

As if the rivets of a longship were being hammered into his skull.

All he wanted was silence, but all he heard was noise.

He considered bashing his head into a rock until everything stopped, but it wasn't an option because he was nigh indestructible.

He trudged to Heorot --each step toward that accursed place causing the pain to multiply-- to beg Hrothgar and his people to please, for the love of god, be fucking quiet.

Instead they mocked his pain.  When he arrived to beseech them to be silent, the shouted and screamed.  The pain was too much.  The breaking point had been passed.

Heorot had to go.
