Copy and pasting/screen-shoting from the Lost Cities Wiki (dam I use that a lot):

Eleanor Olivia Wright was a human first mentioned in Legacy. She was Ethan Benedict Wright's daughter. When she was ten years old, she and her father were killed in a bus "accident" in London. Though not directly confirmed, it is heavily alluded to that Lady Gisela or another member of the Neverseen arranged for this bus accident, killing them since Ethan did not agree to join.

I just realized, we never found out what was going on with her and her dad... plus, why was her name mentioned? They very well could have just said "him and his 10 year old daughter," you know? This very well could be a red haring but what if?

I just feel like there's more to her than being a daughter to this mysterious human.
