Seek Valley is a relatively obscure and mostly unexplored area as it surrounded by steep mountains and is readily accessible only by dragon, as such the Knights of the Dragon's Den are one of the few groups with any knowledge of the valley at all. Located to the southwest of the Dragon Knight's Domain, beautiful crystals grow there. However, it is also very dangerous and no person who has ever gone there in attempt to remove said crystals have ever returned. The rare plant moonlight weed also grows there.
While searching for the moonlight weed, McDohl encountered Ted for the final time before his death here, under the control of Windy. The famed blacksmith, Mace had retired to Seek Valley to live out his days in isolation until persuaded by his disciples to join the Toran Liberation Army.
