Erudon (Korean: 에루돈, lit. Erudon) is a noble family from the Kanavan Kingdom. Famed as the legendary Spell Knights of Kanavan, they are one of the kingdom's most prestigious families whose members have led as generals throughout generations. Although the incident about the killings of the royal family members had put House Erudon in such a great crisis, all the good deeds the family established in the past had helped them slowly regain much of their prestige.
For generations, a Spell Sword has been passed down in the family and was used by Karina herself, then Ronan.
