What is "sigar"

The name Sigar can refer to three people in Scandinavian mythology, surrounding the legends of Sigurd the dragon slayer. One of them only appears as the friend of Helgi Hjörvarðsson in the eddic lay Helgakviða Hjörvarðssonar. The other two appear as the villainous members of the same clan in several sources.
