Many suns

Exploration Stage: Pagoda of Legends
From: Yui
Description: In order for Martha to communicate with the "heavenly archer" in the spirit world, you'll need to collect symbols of his heroic favor. Legend has it that there were once several suns burning in the sky. These suns threatened to destroy the world. But the "heavenly archer" was so accurate that he shot down all the bad suns, leaving only one. Look for the symbol of that last sun in the pagoda.
Completed: You've spotted a three-legged raven. This bird is a symbol of the last sun left in the sky by the "heavenly archer." This will help Martha to communicate with his spirit.
