No, that is true, blood purity is important in determining what a Telethia is. However, my father chose her as his successor because she is wise, kind and her mixed-heritage protects her from transforming into a Telethia. Telethia are mindless beasts, only capable of serving the Bionis. Since I am a pure-blood like most, I am doomed to turn into one when exposed to enough ether.

Before I arrived here, I was sure I died as a Telethia.
