Helion
Hrothgar are separated into two clans, the warm-colored Helion and the winter-furred Lost. In ages past, the Helions of souther Ilsabard served under a singular matriarchal rule, their lives revolving around their queen.
Male Helion surnames are based on the queen they served as, the "clans" named by scholars after the way their lives revolve around their queen, much like celestial bodies to a sun.
