[Ysera frowns slightly, considering that. It was unlikely there was any accurate knowledge of how the Ancients had been bound as crystals or with avatars. Not unless the Ancients knew. But if they didn't even tell their bearers...

She sighed softly.]

I can understand why they wouldn't wish to be bound in crystals. It is not the same as most Ancients I know - they take physical forms of their own. But there are some who choose mortal avatars to bear their power, granting them power and abilities they would not otherwise possess. Such seems the case for you.
