Nite [Morganite]

She’s a tiny weapons scientist who was previously part of Pink Diamond’s court until Pink’s shattering and is now a part of Yellow Diamond’s court, then later given to Sky Diamond. She’s secretive, wily, really condescending despite being barely a foot tall, analytical, and also kind of a dork. She worked on the cluster and really didn’t care one bit. Morganite’s nickname is Nite. Also she's very venomous and hates working with others.

Imperial Topaz is her bodyguard and Coral Pearl is her pearl

She still wears the yellow insignia out of respect for her previous diamond, but also wears the traditional sky court necklace.
