Mana

Mana is one of the metaphysical forces in RJO. Those who can wield mana are called Mages. The first mages in RJO were those from Magical Girl Lyrical Nanoha, but it did not take long until more people with mage-potential were found in the existing ranks of RJO.

Mana is one of the 'harder' forces to utilize, requiring good understanding of math and physics, but once understood, mana is a very versatile force. It can be formed into solid structures, invisible shields, massive attacks, or even protective clothes called Barrier Jackets. It also has healing applications, but in that aspect is less versatile than eg. Force or waterbending based healing.

Mages use Intelligent Devices to assist in the calculations used for many mana-spells, but they are not a requirement to using mana in the first place.
