Most warriors want the cursed sword Soul Edge for its unabated power. Nathaniel William "Rock" Adams, however, wants not power -- but his son's love. To impress his son Bangoo, Rock embarked on a journey to retrieve Soul Edge, traveling through valleys and rivers, across mountains and hills. As he headed south, Rock was attacked and nearly killed in the Alps. Somehow, he found out his assailant was Astaroth, the gigantic golem under the control of the Azure Knight Nightmare in Ostrheinsburg Castle -- incidentally, the bearer of Soul Edge.
