Chess

Meet Chess,

She's the 7th tetramand on board of the shattered diamond; The shattered diamond always needs at least one tetramand on board form the peace treaty between Cpt. Amethyst and the tetramand home world Khoros.
She loves her fiancée Dave and they will marry soon. Besides her obvious love for Dave, she's very self centered and doesn't really care about others.
She joined the crew because she was bored on Khoros and needed some action in her life. Now she's the first mate whenever Lapis or Kyanite (Cpt. Amethyst & Lapis' fusion) is captain.
