Wings

Wings were a symbol of status once the Archangel's were chosen. Those who had once sported white wings and now sported black were the Archangels. And overtime they even began to develop up to 6 wings.

It was found out on Earth they could project their wings when they wanted to, got pissed off, or simply wanted to show status. Their wings come up behind them like a shadow and reflect how full and their shape. For example, Sariel has four wings and fell so her shadow shows 4, black wings that have lost a great number of feathers.

Wings also allow teleportation.
