Eva was an Irish mermaid in 1740. She was turned into a mermaid in the same sea cave as Bella. There is a chance that she also possessed Gelidkinesis, Substanciakinesis and Mecokinesis power. She created the original Tower of Light when the comet was first heading towards earth. She was never seen afterwards, so she either was; killed by creating the Tower of Light or she just swam away after. The comet was named after her as a thank you. She is only mentioned in "Graduation" when Bella was reading about her.
