Recent developments in the One Piece manga have provided new context regarding Prince Loki of Elbaf and the nature of his hammer, Ragnir. Ragnir is revealed to possess the Risu Risu no Mi, model Ratatoskr, a Mythical Zoan Devil Fruit that grants the weapon independent movement and the ability to take on the characteristics of an ice squirrel. The hammer previously served as a guardian for the kingdom's treasure, even acting against Loki to prevent him from accessing certain powers.
Additionally, new information has clarified the circumstances surrounding the death of King Harald. While Loki was responsible for the fatal blow, the act was not driven by a desire for the throne as previously believed. Instead, Harald had fallen under the influence of Imu after entering a pact involving the God's Knights to gain immortality and power. Harald reportedly requested that his son stop him once he realized the consequences of the pact, which aimed to turn the giants into a military resource for the World Government.
