Moral Exemption - Regardless actual moral alignment (Good, Neutral, Evil), the Nephilim is treated as both for the sake of which is more beneficial when meeting prerequisites for classes and feats. This allows an Evil Nephilim to take levels as a Paladin and simultaneously wield an unholy weapon (as per his actual alignment. This does not affect the Ethical axis of alignment (Lawful, Neutral, Chaotic), and that is handle normally.
The Nephilim still takes damage according to his actual alignment with regards to such effects. For instance, a magical circle vs Good would still affect an Evil Nephilim as if it were evil, and can ignore magic circle vs evil.

*For Wings of Light and Shadow, the physical wings that the Nephilim develops fade away, projecting into the different Transitive Planes (typically Astral, Ethereal, and Shadow), though still visible by a corona of pale light and flickering shadow. Because of this, the Nephilim can only be grounded through Dimensional Anchor. The wings cannot be affected otherwise, even with ghost touch weapons as they only link the Material and Ethereal planes. Despite their multiplanar nature, they are an Extraordinary ability rather than a Supernatural one. Visually, the wings can remain hidden unless the Nephilim is flying, but when on display, they shed an effect that acts as either a Light or Darkness effect, centered on the Nephilim.
