If Dwarf Fortress can even have fanfiction considering how open it is, The Incident. Otherwise known as the story of Obok Meatgod. Actually, probably not known, because the Dwarf Fortress community is actively trying to remove all trace of his existence.
The DF Community is known for casually discussing subjects like:
-Locking children in cages with dogs in to train them to be strong as adults
-Dropping babies down a shaft to smash against the floor of the fortress' barracks to condition soldiers for the horrors of war (An actual quote in this thread: "We should probably put glass or a transparent material around the shaft to prevent anyone from saving the babies.")
-Designing traps in order to forcibly breed mermaids to slaughter their children for their valuable bones.
The community that discusses that sort of stuff like an everyday thing is actively trying to forget that The Incident ever happened.
You want details? Sure thing.
Obok Meatgod took enjoyment in killing giants by breaking each of their bones, slowly, before finally killing them. He gathers a group of children and forces them to march. Every time one dies, he stops and watches them get killed by a bear or freeze and drown in an icy sea. Eventually, one child is left; a young elven girl begins desperately attacking Obok to no effect. "She had a nice name. Something beginning with S. I wish i could remember her name."
The player mods in genitals. Obok rapes the child to death.
sweet dreams, children.
