Harriet Heyworth

Harriet Heyworth (3rd April 1830), is a Librarian at the British Museum and a member of The Foundation.

Abilities
When Harriet is wearing her mask she is able to change the colour of her skin and hair. She can also make herself glow.

She can also teleport herself to The Other but remains on the same temporal and physical plane. In other words she appears to have turned invisible but she can interact with objects and people around her as they share the same temporal plane. (Allie's time travelling powers make it very hard to interact because of the different temporal planes).

The first time Harriet wears the Sapphire Mask is when she is captive in Raven's Hill Orphanage. She is made to wear the mask under observation by Amelia Crowe, witnessed by Allie Withinghall-Doyle.

Inspiration
If Harriet were a Disney character she would be Jane Porter
