Charlie Morningstar/History

Charlie was born in Hell to Lucifer Magne and Lilith Magne, the rulers of the realm. Growing up, Charlie tried to see the good in her home and people, despite witnessing the atrocities of the sinners and their victimization during the annual Extermination.

At some point in her early life, Charlie would become acquainted with the von Eldritch family due to her own family's connections in Hell. Charlie would be put off by Helsa von Eldritch's attitude, but would form a relationship with Helsa's brother Seviathan von Eldritch.

However, Charlie and Helsa would over time become fierce rivals and Charlie would eventually break things off with Seviathan, though it is currently unknown what led to this occurring.

Some time before the pilot, she met Vaggie and the two became friends; this would eventually lead to a romantic relationship forming between them.

After the most recent Extermination, Charlie decided to open up the Happy Hotel in order to rehabilitate sinners as an alternative method toward overpopulation. Upon opening the Happy Hotel, Charlie and Vaggie would try to find someone who would be willing to become the first resident of the hotel.

After spending some time searching, they came across Angel Dust prostituting himself on the streets. Charlie pays him to listen to their offer and is quite excited when Angel agrees to go with them and become the hotel's first tenant.

Two weeks pass and Charlie goes with Vaggie to formally introduce the Happy Hotel on Katie Killjoy's talk show to the viewers and all of Hell; despite her promise to Vaggie, Charlie eventually decides to convey her idea via singing. Unfortunately, this backfires when everyone present laughs at the ludicrous idea of possibly rehabilitating a demon in Hell; furthermore, both Charlie and Vaggie are informed that their tenant Angel is currently part of a turf war with Cherri Bomb against Sir Pentious.

Charlie eventually becomes enraged by Katie's continued belittling and mocking of her and the two get into a drawn out fight that is broadcasted on-air; the resulting fight destroys much of the studio and during the chaos, Katie's co-host Tom Trench, is set on fire due to Charlie.

As they ride back to the hotel, Charlie sadly looks out the window and listens to both Vaggie and Angel yelling at each other over what happened. She eventually speaks up and tells Angel that what he did was wrong.

Charlie tries to maintain a positive outlook that there still is a chance it could work, but after trying to calling her mother, begins crying at the realization that her endeavors and dreams might be pointless after all and admitting she has no idea on how to make her idea work. As she glumly thinks about what to do next, she hears a knock at the door; opening it, Charlie is both surprised and horrified to see the Overlord Alastor there. After some thought, she allows the demon to speak and is taken back when he offers his assistance in running the hotel.

Knowing his background and past, Charlie understandably asks why and is told Alastor was simply bored and thought the idea of a rehabilitated demon was nonsensical yet entertaining at the same time. Charlie thinks it over and is reminded that making a deal with Alastor is a grave mistake. She uses her position and family name to get Alastor to work for her, but allows him to work as long as he desires at the hotel.

Upon seeing him bring in Niffty and Husk as employees, Charlie is immediately impressed with the changes Alastor has made and begins seeing this as a new start for the hotel.

Hearing an explosion outside the hotel, Charlie and the others watch in awe and terror as Alastor uses his powers to effortlessly destroy the ship and laser Pentious was using.
