Thorgal is a fantasy adventure series created in the Franco-Belgian bandes dessinées (BD) tradition by Belgian writer Jean Van Hamme and Polish graphic artist Grzegorz Rosiński.

Debuting in 1977, it has incorporated elements of Norse mythology and the legend of Atlantis, as well as science fiction and horror.

In 2002, it was adapted as an adventure video game, Thorgal: Curse of Atlantis, by Cryo Interactive Entertainment.

The comic first appeared in serial form in Tintin magazine in 1977, with the story La Magicienne Trahie.

Translations have appeared in among others, English, Dutch, German, Polish, Italian, Spanish, Danish, Swedish, Norwegian, Tamil and Greek.

BDs (in North-American understanding though, "graphic novel" is the more applicable terminology in this case, particularly where the physical properties of the book format are concerned, the distinction being otherwise a non-issue in native Francophone Europe) are drawn by Rosiński, even for the spin-off albums which sometimes are drawn by other artists.

Commenting on The Archers volume, Rothschild described it as "one of the finest pieces of heroic fantasy I have ever set my eyes on".

[5] After being lost at sea, the ship of Viking leader Leif Haraldson suddenly finds its way home, guided by a mysterious light in the fog.

The jewel brings Thorgal on his first adventure, and binds his fate forever with that of Aaricia (his future wife).

He tells him that he's one of the last survivors of a group of technologically advanced space-farers who came to the planet in search of new energy sources.
