Nick Nocturne is a demon, one of the thousands of children of Lilith, the Queen Mother of Hell--and by demonic standards, he's a truly terrible son.

Born in the late 1800's, the demon that would later come to call himself Nick Nocturne experienced multiple summoning events under magicians across the world starting in 1894, and didn't encounter opportunity to breach a summoning circle until the year 1986, marking his first free-roaming period on Earth.

That first period ended in 1992 after an encounter with a magician who specialized in sending demons back to their realm. The next major summoning event was in 1998, kicking off an extended period of service to a coven leader who promised to grant his freedom at the end of their work. After three years of service and the completion of the coven's desired goals, the summoner betrayed her promise and sent Nick back to Hell.

Summoning was rare in the period between 2001 and 2008, but a lucky break occurred in early 2009 when a novice succeeded in pulling Nick through without placing down any protective measures. He took enough time to get caught up on the year he'd been pulled into and promptly wandered off to be free again.

Years were spent learning how the world now operated and how to get properly settled without alerting anyone who could send him back. Eventually, he met all of his needs as a demon hiding on Earth through the internet and came to find a deep appreciation and humor in the world of horror and the taboo. He found unfiction and saw an opportunity to exist as himself on YouTube without real danger while doing something he cared for that met all of his needs.

All demons except the explicitly cursed and bound can choose their form and shapeshift at will.
In the beginning, Nick Nocturne had no decided form for his online identity, but that problem was, he felt, something to collaborate on with his audience to a certain degree.
 
In the end, his form was influenced by a mix of jokes between himself and audience members regarding the Hocus Pocus character, Thackery Binx, resulting in Nick becoming an anthro black cat with four eyes (and sometimes four arms). As an "internet demon," it only made sense to be a black cat; the traditional form of the familiar spirit (a witch's demon assistant) was a black cat, and the internet was--at least in 2008 through 2010--ruled by cats, or so the joke went at the time.

To this day, Nick Nocturne hosts the Night Mind channel, being himself as both a demon and a creature who has lived on Earth and learned with humanity, growing with this world while staying true to his personality and attempting to rise above his original station as a demon--no matter how much it would infuriate his mother and siblings if they found out.
