The seventh part of the fantasy series devoted to Louve, the daughter of the noble Viking Thorgal Aegirsson and princess Aaricia, knowing animal speech. The girl, along with the dwarf Thjazi, arrives in the Interworld to convince the great serpent Nidhogg to help fight the Black Elves. In turn, the cursed minor god Vigrid and Yasmina, turned into a monkey, move to the land of the Light Elves to seek their support and prevent the destructive plans of Queen Loth. It depends on the success of the various missions of all the heroes whether the Nine Worlds will survive or the creatures of darkness will be able to start a great war and bring the Asgard to an end.

The scripts for the albums of the "Thorgal Louve" series are written by French artist Yann le Pennetier, co-author of several dozen adventure and humorous series, and the drawings are done by the Russian graphic artist Roman Surzhenko (also known from the Thorgal. Teenage years).
