" Everything casts two shadows.

The suns had determined this at the dawn of creation. Brothers, they were, until the younger sun showed his true face to the tribe. It was a sin. The elder sun attempted to kill his brother, as was only proper.

But he failed.

Burning, bleeding, the younger sun pursued his sibling across the sky. The wily old star fled for the hills and safety, but it was his fate never to rest again. For the younger brother had only exposed his face. The elder had exposed his failure. "
