What does Torsten mean?
Torsten joins the god Thor with “stone,” a name of solid strength.
What does Fafnir mean?
Old Norse Fafnir, the dwarf who turned into a dragon guarding a cursed hoard in the Volsung legend. Flag: this is the NAME OF a mythological dragon, not a common word meaning 'dragon'; its own etymology is not securely established, so it qualifies by being a famous dragon-bearer rather than by literal translation.
