Eternity

She looks young, but don't let her looks fool you. She does not have an age but estimates to be over 100 decicillion years old (a 1 with 35 zeros). But you don't know that. Right now, she is disgised as a human. She asks a lot of questions as she wants to learn more about humans and what they do in their lives. She is kind and caring, does not get flustered easily, and cannot die. She only tells about herself when in a situation where a normal human would die. Her younger brother, Infinity, is the only other person who knows her age is unkown. He is protective of her and gets angry easy. Eternity uses the name Kayla while on Earth watching the humans. Infinity uses the name Mark while on Earth learning about there emotions.
