that would be an even worse explanation
a free energy and especially without limit, infinite use
it's like saying that a person would not need to eat and drink to live.
it's another world, but it's not a reason to give such an important advantage
technically it's even worse because the person just does not need anything else (no need to breathe, sun to make vitamin D
"it's nice how it doesen't run out like mana." this sentence is problematic it would merit further explanation
the energy does not leave the body (except in the form of energy loss "heat" and the movement created)
the corp recover Aura from the same external source as the Mana
so for the same person more energy is consumed in the case of a spell
the quality of the body is also important, otherwise a mage would just have to do a spell on himself
and in this case the energy will also be used as AURA is
