Neville was heading to Care of Magical Creatures when he saw his first centaur.
He was talking to Hagrid. They seemed to be in the midst of an argument. Hagrid's face was red, and his gestures even larger than usuall. The centuar seemed a model of rationality. Neville stopped, entranced. Its was marveolus, its coat a deep chestnut and its eyes deep blue.
Finally, the groundskeeper left. The centaur abruptly dropped the disentristed mask, and stared after him, his hands curling into fists and a sneer distorting his face.
Neville shivered. He'd never realized how much danger beauty could hide.
