Caliborn

rude, intractable and irritating

Caliborn is Calliope's aforementioned "brother" that she is working with, and is generally the antithesis of her. He is very rude and ornery (which contrasts Calliope's kindness). Calliborn's writing style is also the opposite of Calliope, capitalizing every letter except u. He writes in a gray tone, abolished as part of the game he has been playing with Calliope for much of his life.

Caliborn has a human body, except for his head which is a skull. Its skin and skull are dark green.

Dark green pants with suspenders and a black t-shirt with the astrological symbol of Ophiuchus, his symbol contains two colors, a gray "U" with a red tilde (~) through it.

Dirk: His human friend who draws for him.

Jane: A human, Jane despises Caliborn, Calliborn takes pleasure in antagonizing Jane by ridiculing her about her somewhat fat body and femininity, talking about how he has spied on her and Roxy, and lying to her about her father saying he was dead.

Roxy: She doesn't talk to him, she prefers to talk to Caliborn's "sister", Calliope.

Caliope: She is his "sister", he and she share the same body, exchanging it every time one is asleep, this is an infinite loop until one of them kills the other and takes over his body. They usually spend time playing chess, which Caliborn hates since Caliope always wins.
