Our heroes met Tien Yu, fended off a party of Infernals & demons & an eye of the Ebon Dragon, and heard the city-goddess's story. She was the then-future-Scarlet Empress' sister and comrade in the retaking of the Imperial Manse, only to have the future Empress feed her into the machinery. When her sister fired the weapon now powered by her soul at Lookshy, she refused to destroy it and instead ended up its goddess.
