Nathan Francis Dorian (9 November 1588 - 17 September 1717) was an English wizard and founder of Ilvermorny School of Witchcraft and Wizardry. A pure-blood of the Dorian wizarding family, Nathan was destined for greatness and was raised with high expectations. Nathan attended Hogwarts School of Witchcraft and Wizardry from 1600 to 1606 and was a ten-minute Hatstall as the Sorting Hat was conflicted whether to put him into Gryffindor or Ravenclaw. Finally, the Hat gave Nathan a chance to choose, and to appease his family, he chose Ravenclaw.
