The Barony of Brigham was a Manticoran peerage.
In 1496 PD, it was the furthest south land claim on Sphinx, laying thirteen hundred kilometers south of Twin Forks in a mountainous area. In May of that year, Aldona Zivonik of the Sphinx Forestry Service attempted to pilot a Dromedary transport to the barony with urgently needed supplies for the five members of the Brigham family that survived the Manticoran Plague.
