He also learns about Judam, the Queen of Green, a dark object that collects and consumes beautiful objects and destroys all in her path. Despite the danger, Kouga wanted a way to find the Fang of Sorrow; Meru didn’t know anything of it, but suggested to seek the Guardian of Wisdom to possibly learn more. Despite the warnings of danger, Kouga insisted to go and Meru acted as his guide to the Temple of Wisdom.
