Kurt, Sapphire, and Stephane used to be one character who had some time with his consciousness transferred to different bodies. I saw the Trill in TNG and DS9, specially with DS9 and Dax, I decided to use the symbiotic method. Kurt and Sapphire because a character with multipersonailty disorder. Kurt/Sapphire is a humanoid shapeshift (also can shapeshift into animals and creatures), S/he is a gender shifter which means that s/he can be female when having a female personality which would include Sapphire, Max and Sally, but can have be male when being Kurt. Right now there is only one male personality. Her mother was a Siren turned Vampire during a miscarriage with a Vampire prince named Kurt Black. Mommy was known as Sapphire Ptah, but after Ptah disappeared, she changed her name to Sapphire Gemstone.
Stephane became a symbiotic creature. He tends to prefer Vamps. I thought it would be interesting for him to be named after a Sun god since most media has vamps be allergic to sunlight. So his name because Stephane Ra.
I have liked Egyptian mythology for so long. Once I thought they were bad, but then I decided that they are cool.
