House Seamel is probably the least influential of the Noble Houses, a family web consisting largely of farmers and horse breeders who really only came into increased prominence with the marriage of Freia Seamel to Talus Kahar XIV. This surge in power for the upstart House has earned some disdain from other Nobles, particularly House Zahir, but even some who fall under the wildcat banner of House Kahar.
House Seamel's coat of arms is, "A knight mounted on grey horse, on green."
