These siblings are both named Sam, referred to by Zandra as "Big Sam" and "Little Sam." Big Sam is clearly an elder brother, attempting to shield his little sister from whatever harm may come to her. Their parents died years ago, so the adults of Charlesburg have pitched in to take care of these orphaned siblings. Big Sam does his best to come across as a serious man; but is still an adolescent boy who blushes when Zandra looks at him. Little Sam may be shy at first but loves to tease her brother. These siblings are the first people that Zandra encounters when she enters Domhan and are certainly an informative introduction to this mysterious new world.
