((Just had an idea yesterday that might be good.))
A few days later, Koga was laying back on the gigantic tree-top, dreaming quietly. In his dream, he saw himself walking in the forest, many thousands of years ago. He stumbled upon a large black wolf, one of his best creations in the way of animals as he often thought to himself. The poor thiing had hurt its leg but Koga knelt down and healed the injury gently, being as soothing as he could. The wolf then got up and nuzzled him lightly, thanking the god in its own way and licking him on the cheek. A human had stumbled upon them at tat moment, recognizing Koga as a god, and spread the tale of how the god had a connection to the wolves that was very special indeed. This led to a stronger worship of the creatures in connection to Koga and how all humanoids listened as closely as they could to the wolf song, learning it in order to please the mighty god. This was, of course, in the oldest of days when the humanoid races were just developing.
