you're chained to the floor of the hall and a lot of gems are looking at you, laughing and mocking you then a deep and cold voice then spoke

???: Silence her voice sounds like an hush of sadness and depression

She is blue diamond, one of the four diamonds, she is really tall, she have her gem on the Middle of her chest, she wears a long cloak that obscure her body and she have her personal pearl besides her

Blue: who are you, little creature?
