No way soowon made it heaven

The white dragon stated that all souls end there, even without reverencing the same God. So I guess it was an indirect that there is no hell, just heaven (that is not there either, it is another place where the dragons wanted to take Yona to).

I love this idea that there is no hell or heaven, just...peace. Genuinely makes me so emotional. Pain manifests in so many forms. Living is punishment enough. Everyone deserves peace after death.
