I honestly have no doubt that Edda, after however she got the knowledge of the art, experimented and cultivated her powers on her own volition. She just happens to have been that batshit crazy.
Necromancy is definitely a void art though, see as there are ALOT of voidsent in Tam-Tara HM, though that could also be her using her new powers to tap into the void energies already present in the area, seeing how the Lambs of Dalamud used it to to revive Galvanth the Dominator in the Story mode version. So many possibilities :3
