Twisted Histories! If you're on Twitter, tweet @twisteryhistory to receive a tale of a bizarre historical event!
It uses an upgraded version of my Histories of the Blasted Lands that was made in Tracery, a script for generative grammars that allows things like names to be generated in far higher detail and complexity.
I've got a few more ideas for bots in the works...
EDIT: this little bot is honored to be praised by TTRPG's most prolific possum!
