Creaturina doesn't know it, but she is the daughter of the universe's only sentient planet, Nightmare. Creatuie came, accidentally, to Earth when she was only a 1000 year old child. She is now 4000 years old. The first 1000 years of her life, on Nightmare, were spent naked and simple, she never talked, and spent all her time killing things to eat. She is extremely good at killing things. She is also off the intelligence scale, as well as the scale of indestructibility, and she never forgets anything... literally. It didn't take her long to learn to wear clothes, and to amass a fortune in land and wealth on primitive Earth, but that's another story.
Since she came here, Creatuie has been hearing a very faint kind of celestial music on certain nights, a music that has been growing steadily stronger over the millennia. When she hears this music, Creatuie often has an overwhelming urge to strip naked, back to her childhood state, and to climb to the highest battlements of her castle, and sit, unmoving, all night, trying to understand the music only she can hear. She does not know it, but the music is her mother, Nightmare, calling across the millennia and light years to her lost daughter.
