Lore: in the ancient years Ni' Vex came from the underworld to cover earth in darkness with her shadows. The ionians though imprisoned her inside a box and hid it inside a catacombs. the same catacombs years later zed walked in and opened the forbidden box against his master's will, unknowingly releasing a shadow demon with no real form, just a shadow. Ni 'Vex. Zed stole some of her powers and for quite a while rendered her unable to appear. But now she is back, stronger than ever, ready to pledge the world in eternal darkness. The more she fights the stronger she gets, and with the ancient runes that kept her at bay lost in history, there is nothing to stop her.
