...The two assassins who had held back, ready to follow their leader, watched as he ran towards Adam. They saw he was unbelievably fast, just a dark blur driven by anger. He moved like a super-tight spring let loose, planning to kill Adam (Eric) right away with the two glowing knives he held, magic shimmering around the blades.
They saw him lift one knife high, aiming to stab Adam in the neck to silence him forever. He was only a few feet from Adam now, the knife raised high, ready for the final blow.
But at that exact moment, when the charging assassin was right in the middle of his attack, raising his knife to kill, his head suddenly, terribly, and impossibly came off his body. It wasn't a slow cut you could see from a sword. It happened so fast that the two watching assassins couldn't even see what did it.
