Vampire Academy for young vampires and dhampires.
The Mori are the good vampires. They don't kill to feed. Sunlight does burn them a little easier. They are the only type of vampire able to wield one of four powers - Earth, water, wind and fire.
The Dhampires are half-human, half-vampire with the strength of a human reflexes of a vampire. Strogi have killed at some point while feeding. They are the immortal ones. They get stronger with each kill. They are unable to go in sunlight. They can be killed by decapitation, silver stake through heart or burning. The dhampires must become guardians to protect the Mori from Strogi.

Welcome to the Vampire Academy where we learn about them.
