I ended up writing a whole page of backstory because I felt inspired, but I'll cut it to just the main bullet points here. I'm going to keep this character in reserve for possible use in an actual game someday.
Kasimir, Tiefling Cleric of Ilmater
Born to a devil-worshipping cult centered around his cambion father. Criminal youth, subject of familial abuse and racism. Eventually he was caught as a result of crimes and nearly lynched, saved only by the intervention of a cleric of Ilmater. The cleric died to rescue his sorry ass and Kasimir suddenly realized that most people are not constantly horrible and wracked with guilt. He joined the church of Ilmater to make up for bad deeds. Is still wracked with guilt, but pretty good at hiding it.
The person he dreams of is himself as a regular human. He's over-corrected on his moral compass and absolutely hates himself for things both in and out of his own control.
