Cyndi Black: Daughter of Dr. Black & Dr. White. Owner of the portal pendant, Black Alice. Popular at School (lol). Everyone envys her artistic genius but she is not satisfied with herself (believing that her achievements were not earned but rather given to her at birth). She is an engineered human born in a lab. Her physical features were designed according to Dr. White’s idea daughter with porcelain-like skin. Only she can operate the portal known as Black Alice. Although she is engineered, she has attributes that make humans human. She has crushes on her classmates like any other girls her age but they seem to disappear (move to another school, died or grew super sick). Figures that it is Dr. Black’s doing... because he only wants Cyndi to love Dr. White and himself (keep her safe, in a way but I'm pretty sure they're pedobears... or not). In Otherland, people are used to calling her Black Alice because she and the pendant are like one.

Black Alice: A device that is designed by Dr. Black and White to cross between their world and another one they like to call Alice’s Otherland. The sole operator of Black Alice is Cyndi Black. She carries Black Alice around her neck strapped on a black cord. The pendant is also black except for the designs in white (pearly). It is as thick as a locket/pocket watch but is sealed in a way that it cannot be opened. What's inside is unknown. Cyndi never takes it off. When separated from Cyndi, Black Alice is automatically deactivated. The only one who can reactivate it is Dr. Black and Dr. White (combined).

Otherworld: Otherworld is surrounded by Barrenlands. Castle of Cards in at Otherworld's center surrounded by "water".
