Unleash Soul Equipment
The Oran Mor is the song of the universe, its sound having said to have been the first thing that caused the realms of Muspelheim and Nifelheim to become active and spit their power into the great ocean, creating life. However, it is tied to all things and items and when it is applied to them it can become a powerful force that enhances weapons and armour.
When a Sentinel has gathered the scrolls of songs from around the realms the Oran Mor starts to gather about him, allowing him to enchant his items to empower them and help him battle the enemies. With different songs having differing mystical values.
