Tessa Lancaster, also known as Beth Darwin, is an antagonist in The Demon's Light. She is the half-human daughter of Cicero.


Tessa has long red hair, dark eyes, and tanned skin. On her jawline is a pale scar that stands out due to her dark skin tone. She is 5'7 ft tall and weighs 130 pounds. She doesn't have a strong sense of fashion and often wears dark clothing.


Tessa has always been the silent, observant type. While well-mannered, she is in truth not to be trusted. Like her father, she will do anything to complete her goals, not allowing anyone to get in her way. She can be sneaky and a skilled liar, as shown in the later episodes of Season One.


Tessa Lancaster is the daughter of Cicero and Melody Lancaster, born due to an affair where Cicero was studying humans, interested in his father's creations. Growing up in unknown circumstances, Tessa is extremely loyal to her father, willing to follow any instruction or order given down by him.

Interested in helping her father find the new reincarnation of Xeren's soul, the "host," she joined a Silivian laboratory specialized in angels and demons, as an assistant. Using the alias "Beth Darwin," she earned herself the reputation of being a hard worker and gained the trust of the lab scientists, even forming a relationship with Steven Devlin.
