This is the magic imbued in the horn of reconciliation by the dragon. When the horn is used, an oppressed Magmar receives the dragon's protection and becomes invulnerable to injuries inflicted by other Magmars away from the battlefields. The magic can be activated by hailing the victim's name into the horn. The sound of the horn acts as a reminder to all warriors of the ban on enmity and violence within the Magmar ranks. To dispel this magic, the owner needs to break the Radiant Sphere in their backpack.
