Mikael Part One.

The Mikaelson Family is a powerful family whose line dates back at least to the then Kingdom of Norway in the late 10th century with Mikael and Esther, a wealthy landowner and a Viking warrior, and a housewife and a witch, respectively. At the beginning of the 11th century, the family was mortal until the loss of Esther and Mikael's youngest child, Henrik to a werewolf attack spurred them to use Esther's magic to turn Mikael and the rest of their living children into the world's first vampires, from whom all Vampires are descended. The Original vampires are known as the most powerful supernatural beings in the world, but the Mikaelson family is also known for having members who are witches and Hybrids as well.
