The Apologists believe that in the space between life and death, one is not held on trial. Instead, one receives an intervention with their no longer living friends, enemies, loved ones, and ancestors. One is made to feel sorry for every wrong they've ever committed, to apologize to themselves, the dead, and the living (this is where magic and miracles come from), to have a very cathartic cry, and then a deep and pleasant rest, well deserved.
Some have criticized this belief as a means by criminals and profiteers to stomach the abuses they commit in life. "We'll all experience the same things in the end, so what's the consequence, one way or the other?"
Others find comfort knowing that they will always find forgiveness, and feel empowered to be more forgiving in life. As well, their impact on the world has been vast, and in many cases quite positive.
The Apologists are overrepresented relative to the general population in the field of mental health. They also led the movement to dismantle the prison industrial complex that persisted into the early 21st century.
At the same time, every Carnival King, May Queen, and Fool has been an Apologist, and were empowered by popular support from the Apologist majority.
While many today still debate the merits of this new movement, none deny the influence it has had across the world in such a short time.
I imagine this as a mid-Apocalyptic, Epic Dark Fantasy setting that happens to be set in a technological and culturally Modern world. Something between Game of Thrones and Final Fantasy XV.
You could throw out the explicit reference to the 21st century and embed it in a more traditional fantasy setting and use the Apologist belief system as the source of "magic and miracles" within the setting.
