The Janus Branch is one of the five branches of the Cahill family. It was founded by Jane Cahill. Jonah Wizard is the only significant Janus to appear in all of the books, but his mother, Cora Wizard, the leader of the Janus, appears several times, along with his father, Broderick Wizard.


Jane Cahill was the second-youngest Cahill (presumed first-youngest until Madeleine's existence was discovered). She was closest to Luke because he cared for her and loved listening to her music and poetry. She was only 10 years old when she saw Luke trying to convince his father to give him remaining clues in Gideon Cahill's lab just before the fire. Afterwards, she ran away to England with a broken heart, disguising herself as a man named John and became a famous artist. Art became the only thing that alleviated her pain. She passed this down her lineage through the serum, creating a line of people who cared more about art than anything else. This was demonstrated in One False Note where all the Janus were worrying more about rescuing the art in the stronghold than Dan and Amy escaping.


The Janus crest is a green shield with a white wolf standing as if it was guarding something important with outstretched claws and a head, turned the opposite way, with its tongue flailing out. Below the crest
, as with all Cahill family crests, is a greyish-silver scroll that reads "JANUS". The Janus' simpler crest (pictured right), is the same shield shape, just without the scroll, and only the head of the wolf is visible.

The Janus mascot is a wolf, with its head turned to the right with a bearing tongue, and its front paws clawing the air. It symbolizes the Janus' elegance and wisdom, but also the willingness to kill when necessary; all Janus have a natural gift in martial arts.


Members of the Janus branch are very artistic and creative, but can also be extremely impulsive. They are writers, artists, designers, and musicians; almost all famous directors, songwriters, painters, or poets are Janus. As revealed in The Emperor's Code, the Janus also excel in the martial arts, being beautiful and amazing to watch (unlike someone shooting a gun). Janus can use their talent for the good of the world, but they can also use it for the Hunt for the 39 Clues.
