How did Eleanora die in seer of shadows?

Eleanora wanted her sister peg to be treated as a daughter to her aunt or adopted mother. Her aunt Mrs Fredrick Von Macht wanted Eleanora's wealth. Until Eleanora signed the papers to say that her aunt gets the money Eleanora didn't get any food or water. She refused to sign till Peg was treated as a daughter instead of a servant. Eleanora was eventually isolated with just her bedroom. She asked for doctors but Mrs Von Macht wouldn't get any help till the papers were signed. Eleanora got really sick and died of starvation. Peg dressed her and buried her. After her death Mrs and Mr Von Macht inherited her wealth and kept treating peg as a servant.
