Kai'sa

Kai'sa was taken by the void as a child. But instead of letting it consume her, she fought off its temptations. While in the void, she managed to get control of a void creature, but it also had a drawback. The clothes Kai'sa wear is not clothes at all it is the void creature, learning and adapting as she does. She is unable to take it off, but it also grants her some powers. Now, she has managed to escape the void but with the void creature still on her.
