Dagar was a sword and sorcery series, set in a mythical past of warriors and wizards. There were a few secondary characters (Durak in #7, 12, 13; Torgus in #9, 10, 13). Durak originally appeared as "Duroc" in Mystery Comics Digest #7, 14 and 15, then was renamed for his debut in Dagar the Invincible.
Don Glut also tied in his other Gold Key characters such as Tragg and Doctor Spektor. In #5, Tragg's Neanderthal brother Jarn appeared. Tragg cameoed in issue #11. In issue #13, the story actually crossed over into and was concluded in issue #15 of The Occult Files of Dr. Spektor.
