How do fledglings become full vampires?

the thing is when a vampire turns you,you onley become half vampire.it will take you at least ten years to turn full vampire.you will hit a thing called the purge.but,some say there is a witch called perspone and she is said to have children that are born vampires.and yes,vampies age very slowly and have lighting speed.some say they have super spit that can heal deadley woundes.if you have any more questions about the immortles you can reach me at 936 239 7150 or at my email carolynplymale@Yahoo.com
