What these people wanted was a form which naturally had the urge to respect the land and cherish life. They wanted a form that had moral codes as part and parcel of their very being, not something that they would learn and discard during childhood. When the Dreamlords sympathetic to the human disinters gathered around to hear their pleas, they mused long and hard as to what to do. Finally they decided to grant the people their wish. The Dreamlords realized that animals had exactly what the humans wanted.
Animals have their own innate sense of nature-based morality.
Unless pushed beyond their limits, animals do not hate. Hate, the Dreamlords saw, was an emotion felt regularly only by the more intelligent sentient creatures. They sent the people on a quest which finally lead them the island of Nirva. There the people built a great temple dedicated to the spirits of the animals and nature. After many years, they were finally ready.
