Master Crusoe is not as old as he looks, but all the young familiars see him as this wise and worldly creature, unfathomably deep in experience and personality. The truth is, Master Crusoe is a mild dragon who, like his mage, Master Robinson, favours the calming properties of wind and water. Most folks see dragons as creatures of fire, aligned with conflict and passion and energy, but dragons work all elements equally, making them malleable and powerful. But it is just as likely that a dragon will favour the earth, or sky, or rivers and seas, over the boiling fire of his own heart.
Still, I think Master Crusoe enjoys that little touch of wildness that the youngsters speak of, and certainly makes no moves to correct their rumours.
