The centaur didn't answer. He had astonishingly blue eyes, like pale sapphires. He looked carefully at Harry, his eyes lingering on the scar that stood out, livid, on Harry's forehead.

"You are the Potter boy," he said. "You had better get back to Hagrid. The forest is not safe at this time — especially for you. Can you ride? It will be quicker this way.

"My name is Firenze," he added, as he lowered himself on to his front legs so that Harry could clamber onto his back.

There was suddenly a sound of more galloping from the other side of the clearing. Ronan and Bane came bursting through the trees, their flanks heaving and sweaty.

"Firenze!" Bane thundered. "What are you doing? You have a human on your back! Have you no shame? Are you a common mule?"

"Do you realize who this is?" said Firenze. "This is the Potter boy. The quicker he leaves this forest, the better."

"What have you been telling him?" growled Bane. "Remember, Firenze, we are sworn not to set ourselves against the heavens. Have we not read what is to come in the movements of the planets?"

Ronan pawed the ground nervously. "I'm sure Firenze thought he was acting for the best, " he said in his gloomy voice.

Bane kicked his back legs in anger.

"For the best! What is that to do with us? Centaurs are concerned with what has been foretold! It is not our business to run around like donkeys after stray humans in our forest!"
