The Lost: "These are the Hrothgar who have found themselves bereft of a queen and—typically after a lengthy period of mourning—struck out on their own. One can assume with a fair degree of certainty that any male Hrothgar encountered beyond Bozja's borders are of the Lost, as they are far more likely than Helions to abandon their settlement and embrace a nomadic lifestyle. Female Lost are also known to exist—individuals who have, for whatever reason, renounced or refused the ruler's mantle to pursue life on their own terms."
