Hei Blackwood

Hei Blackwood is an ancestor of the Blackwood Family of MacGrayn City who is featured in the episode "Hei Blackwood: Ancient Blackwood & the Elephant of Lohan" as the protagonist (an inverse to her descendant and modern counterpart's usual antagonistic role)

During a trip to India she encountered Ezekiel the Leopard who was also after the Elephant of Loh for a personal goal as well as the engimatic twins Li and Lu who serve as guardians of the Elephant of Lohan.

Personality
Hei, unlike Heidi, is bold, adventurous and intelligent with a liking towards mystery and riddles.

Information
Hei was born in Switserland, but was conceived to be Scottish

Hei is short for Heidi implying that she might have the same name as her distant descendant; she was named this in order to make the connection easier for the audience yet also identifying her as a "relative and not the same person".

Hei and Ezekiel the Leopard are not related themselves but their descendants, the modern inhabitants of 777 Magnus Cresant, MacGrayn, are related to both sides.

Hei being the niece of the Belinda counterpart of her timeline makes the two the only ancestors of the Blackwood family of said time period to be related, Li and Lu appear to be celestial children who are the ghostly guardians of the elephant of Lohan, Ezekial is another matter mentioned above and the Boris and Grandpa blackwood counterpart were not confirmed related to any side of the matter.
