Stages-=
The Pearls=-
The angelics eggs are vastly different than the typical dragon egg, they closely resemble large pearls with a feather of their parent providing a safe environment for it should the egg get lost.

-=
The Hatchlings=-
Once the eggs make it past that vulnerable stage, the angelic hatchling begins it's life. As pure as the sky dragon race is, this is a crucial period of time in the young dragon's life when it must be given great care and consideration into the environment it is being raised in.
Also, with the sprouting of their new little wings, they will want to fly..but keep a close eye on them because they can injure themselves greatly with their curiousity in flying.
Just like any young child, they take on the attributes and beliefs of what they are around...so be wary when handling one of these gentle creatures, lest it's nature be turned into something terrible.

-=
The Adolescents=-
Even at this stage of life, the teens of this species tend to be much more obedient than those of the others. There are always exceptions to this rule...as there will always be the rebellious types born into the pure race.
One common cause of such rebellion to their caretaker would be the attraction that starts to flourish at this stage of life. Just like human teenagers, this attraction to the opposite sex can make them unruly and angsty at times...
Their ability to fly is much better than what it was at their younger stage, but their wings are still growing and it is highly unadvised for them to carry heavy things or stay airborne for too long.

-=
The Angels=-
Finally all the hard work put into raising the dragon has paid off. At this stage the dragon's are able to reproduce, their wings have grown to their full length and their magic is as powerful as it is going to get. Here they will become loyal to the very end to those who have managed to care for them, protective of those they love...or perhaps the exact opposite.

-=
The Archangels=-
Is there a possibility of reaching a higher stage than that which has been recently discovered?
