Only a blur, sharper than knives

Arrow shook his head. “I don’t care for it. Your kind aren’t worthy of
names. If I kill you, I’ll think of you only as number nine.”
“As you wish,” the vampaneze said coldly.

They clashed.

It was a short, brutal battle. To any watching human it would have
appeared as a blur, but Larten could follow the action with his heightened
senses. The pair tore at one another with their fingers, nails sharper than
knives. The vampaneze almost slit open one of Arrow’s eyes, but just
missed and scraped his skull instead. Arrow in return nicked the flesh
beneath the vampaneze’s throat.
