Fhampirs.

The Dhampir is a half blood vampire.

They are created when a person is forcefully turned but dies in the process.

They are generally weaker than Vampires and have both a blood core and mana core.

A True Dhampir, however, is a species of it's own.

It is a creature that is created when a vampire marries a human, or when two Dhampirs get married.

These have only one dhampir core and are stronger than Vampires.

The true Dhampirs, during the time of Xavian, are extinct.

Probably because vampires did not like to associate with humans.

Just like vampires, the dhampirs, can also create lesser creatures.

These include a wide variety of monsters, thralls, or very rarely, even vampires.

Slavi.

A slavi is a zombie-like thrall kind of creature.

But unlike the walking dead, they have a mind of their own.

They are not forced to serve their creator, instead, they choose to.

Slavi are usually core-less, since they are no longer a living creature and rely on their former abilities.

However, their Master could choose to upgrade them by creating a core for them.

When a creature is turned, it would retain it's original capabilities until their creator chooses to change their ability by creating a core.

As more creatures appear, this list would keep getting updated.
