Those who died in battle or in sacrifice as war captives went to join the sun in the sky after death. Sahagun reports: "It was said that they lived together where there was a place like a desert. When the sun appeared, when it came forth, then they made a din, they howled; shields were struck together. " The place was full of thorny plants. After four years, they were transformed into hummingbirds, huitzitzilti, butterflies, and other brightly-colored flying things.
