Yohewah Uyoayeldvi, or “The Great Sorrow,” is a period of time in Nunnwi history that represents their people's greatest tragedy. It began with the dying of their home, The Great Tree Uncimaka, or “Great Mother,” on Innatraea. Many Nunnwi are still scarred from this event of chaos, violence, death, and sadness. Even eons later Yohewah Uyoayeldvi is a darkness upon the Nunnwi psyche.
