Brade, known as Quake in the English adaptation, was a legendary Spider Rider from the Inner World's history. He earned his reputation through a unique ability to defeat enemies without taking their lives, a feat celebrated in plays and stories across Arachna. He undertook a significant journey to the Kingdom of Nuuma, transporting one of the Oracle Keys—specifically the key enabling Nuuma Castle to float using the Oracle's power. This key was entrusted to Nuuma's sanctuary, and Brade was last recorded traveling with the Sea Buff Mariner, also known as the Lost Mariner. Following these events, Brade retired from battle, assuming the appearance of a small, elderly man residing in a forest. In this secluded state, he provided guidance and aid to Hunter Steele and Aqune during their struggles. A notable interaction occurred when Corona and Aqune vied to impress him with their culinary skills in a cooking duel. Later, a startling truth surfaced: Brade was deceased, existing as a spectral entity. Despite his physical absence, his spirit fulfilled a crucial prophecy as the eighth Rider required to awaken the Spirit Oracle, allowing the ritual's completion alongside the living Riders. This spiritual intervention occurred during the final confrontation against Mantid, affirming Brade's enduring legacy and importance even beyond death.
