Then he came back to the lodge and a voice within bellowed loudly and asked him what he wished. He asked who was in the lodge and a swallow flew up out of it. The West Wind looked at this bird, amazed and asked how it could bellow so loudly. The swallow told him that this was the lodge of the Winged God, that the nest in the tree was his nest, and the egg in the nest was his egg. Then Eya said he would like to see the Winged God. The swallow said that if one saw the real Winged God that one would be heyoka, and must forever act and speak in an anti-natural manner. But, if one saw Heyoka, then one need not be heyoka. Eya said he would like to see the real Winged God and also Heyoka. Immediately, there arose from the lodge a shapeless thing like a cloud of smoke, but with a huge beak like an eagle. In the beak were four rows of sharp teeth like those of a wolf. It had an eye and its glance was the lightning. Its voice was the thunder. It had four-jointed wings. It had no feet or legs, but eight toes, and on each toe were enormous talons like those of the eagle and each talon was as long as an eagle's wing. It seized the egg in its talons and shook it and the noise was the rolling thunder. As the West Wind looked at it, it became like a giant man and spoke to him. It said that because he was so brave and had looked at the Winged God without falling down or running away, that he should forever be the companion of Wakinyan, the Winged, and that he should aid this God in cleansing the world of filthy and evil things. When the Heyoka said this he vanished. Then the sparrow said that from that time on, as long as mankind had ceremonies for the Gods, the West Wind should have precedence over all Gods, except one; that when he had done the work he was going to do, he must make his tipi on the mountain at the edge of the world and have that for his abiding place; that his direction would be the first established and the first recognized.
