- The caste of Thralls (slaves and landless workers) – they are often physically ugly (sometimes even deformed) but strong, hardworking and useful members of their community, though men and women live together they are unmarried and their sons have names like Weather-beaten, Barn-cleaner, Sluggard, Shorty, Fatty and Stinker, while their daughters have names such as Skinny-hips, Fat-calf, Gossip and Beak-nose.
- The caste of Freemen (landholding farmers, artisans and soldiers) – they are skilled and industrious workers, eg, the men are skilled at wood carving, working the plough, and building wagons, barns and homes, while the women engage in wool-spinning and weaving; their hair is tidy and they wear nicely tailored clothes; they are married (they've “exchanged rings”) and their children are described as red-haired and keen-eyed; their sons have names like Manly, Brave, Swordsman, Soldier, Smith, Farmer and Trim-beard, while their daughters have names such as Sensible, Smart, Swan, Lady, Shy and Vivacious.
- The caste of Nobles (aristocracy, military leaders and shamans) – their skin is pale, their fingers are long, their hair is blonde, their eyes are piercing, they are wise, understand the language of birds, know the runes, and the spells associated with them; the men are skilled at using weapons, horse-riding, hunting, swimming and war – causing them to own large estates and treasure, with which they are generous; couples love each other deeply and their children have names such as Noble, Kinsman, Heir and King.
The three castes share the same divine, paternal ancestor – being Heimdall the White, as it says in the Voluspa:
“Heed my words, all classes of men, you greater and lesser children of Heimdall [J Crawford, The Poetic Edda, 2015, Hackett].”
