Rathgar is from a clan of dwarves who live in the village of Macridi in the Palkar Forest of Druma. This village is not a solely dwarven village but the dwarves in it are part of the same clan as the nearby dwarven city. His family is responsible for running one of the lumber mill that provides wooden beams for construction in the city and in the nearby mines.
Rathgar spent his childhood exploring the woods and caves near his home. In his explorations he met several druids who would teach him some of their knowledge of nature and of the general area in which he lived. As he grew older Rathgar helped out around the mill performing odd jobs for his father. As part of young adulthood in his clan, male dwarves had to serve in the militia and also in the mines. While he did not enjoy the mines as much as doing work outside, he still found it enjoyable learning about stone working and appraisal. While serving in the militia Rathgar showed great skill in survival and reconnaissance. While gathering reconnaissance Rathgar developed an interest in mapmaking and exploring unknown places.
While his company was out on patrol for a standard mission looking in on nearby villages, a goblin raid occurred on Rathgar's home. Though the goblins were driven off there were casualties among the dwarves, including Rathgar's mother. Upon returning to the village the militia immediately followed the trail of the goblins and wiped them out.
Afterward Rathgar couldn't stand to remain in the village where his mother was killed and he began to wander the wilderness, hoping that it would help to soften the pain of his loss. As he dealt with his grief he began to make his way south, deeper into the wilderness, with the intent of mapping out safe routes for future travelers. As he traveled he learned how to listen to nature and being able to tell how creatures around him were reacting to his presence. He would also come upon others from time to time and if they were in need would offer to give them a hand. Heading south from his home in Macridi, Rathgar was not sure what he would find but he eventually came into the town of Falcon's Hollow and decided that he would stay for a time and see if he could find any work in the area.
