Flipping through an old paperback of myths over coffee, I always get sidetracked by the personalities—Norse myth is basically a family soap opera with gods and giants. The main crowd people point to are the Æsir: Odin (the Allfather, wisdom and war), Thor (thunder, storms, and bludgeoning giants), Frigg (Odin’s partner, associated with marriage and fate), Baldr (the almost-too-good son whose death shakes the cosmos), Tyr (law and heroic sacrifice), and Heimdall (watchman of the gods). Loki often pops into that list because he’s so central to the stories, but he’s a slippery figure—more trickster and blood-tied to giant-kin than a straight-up Æsir with a neat job description.
Then there are the Vanir, another divine branch who become part of the main cast after the Æsir–Vanir war: Njord (the sea and wealth), Freyr (fertility, prosperity), and Freyja (love, magic, and battle-cat energy). The sources that preserve these names—the 'Poetic Edda' and 'Prose Edda'—treat the pantheon as messy and overlapping rather than a strict organizational chart. Family ties, hostage exchanges, and mythic politics mean gods switch roles, betray each other, and sometimes function more like archetypes than fixed personalities.
If you want a place to start, skim translated selections of the 'Poetic Edda' to catch the raw poems, then read snatches of the 'Prose Edda' for context. Modern retellings and games like 'God of War' or 'Assassin's Creed Valhalla' steal freely from these figures, but the originals are often darker and stranger. I keep coming back because every re-read reveals a different shade to Odin or Freyja, and that unpredictability is the best part.
