Despite the language that spells are performed in, syllables and phonetics of spells are important and, when performed wrong, can cause spells to not work as intended or not at all. Cleo Sowande, however, has performed a number of black magic spells in Yoruba. Dahlia and Freya Mikaelson perform spells using a yet to be identified ancient magic in Old Norse, similar to modern-day Norwegian, Icelandic, Faroese, Danish and Swedish with some Serbian/Croatian words in between. However, witches who practice other forms of magic have been known to use spells in different languages for example, the Nine Covens of New Orleans, which practices Ancestral Magic, performs their spells in French or French Creole, while the Travelers, practicing Traveler Magic, typically perform their spells in a language similar to Czech. The majority of spells used by practitioners of Traditional and Spirit Magic are spoken in an ancient language very similar to Latin. Nature demands balance and as such, every spell has a loophole, no matter what magic is used to cast the spell. Spells are bound by Nature and can range from simple to complex, depending on the need of the casting witch.

Esther bound Klaus' werewolf side, causing Klaus to murder his mother. The truth of Klaus' parentage was revealed when he transformed into a werewolf following his first kill.

Klaus, Elijah, Rebekah, Finn (Casper Zafer), and Kol (Nathaniel Buzolic in TVD Daniel Sharman in The Originals) were gifted with incredible abilities - but vampirism has drawbacks, and Nature soon rejected them. Using the blood of Tatia Petrova, another doppelgänger descendant of Amara's, Esther cast an alternative immortality spell that turned her children into the first vampires. Fearing for their children's safety, Esther and Mikael turned to magic. The Original family lived peacefully until 1001 A.D., when their youngest son, Henrik, was killed by a werewolf. After that, the Mikaelsons fled to the New World, where they settled in a werewolf village that later became Mystic Falls.
