Normal form.
No, she is not a re-design or a new character.
This is simply the alternate form Farrin takes when her pendant charm is used.
In the beginning, she was only able to take this form during emotionally stressful times and it was uncontrolled when it would happen. Later on she became able to control when she transformed and discovered that she has the ability of Astrakinesis.
Astrakinesis
The ability allows her to teleport herself, objects, or other beings to the astral plane where spirits reside. She can allow the living to see the dead, and allow others and herself to temporarily become a spirit. She can also view or send a message through dreams, although she is unable to change or alter anyone's dreams.
