Lapin tietäjät ("Sages of Lapland/North") is a non-fiction book about the practice of northern magic and a riveting dive into the its folklore, where the dead are raised, "corpse-mould" is drunk, and the spirits of the deceased are recruited as reindeer herders.
 

It tells the story of the Sages of Lapland, who have also been called "the witches" - just like the shamans. Although the shaman drum fell silent in Lapland centuries ago, and the era of soul-journeying shamans (noaidis) was over, their followers who practiced magic were still called "witches" for a long time. However, some elements of the ancient shamanism were inherited by these new semi-professionals of the Otherworld.

​

The northern sage relied on the dead people he raised from the underworld and the faceless folk of the dead ("kalmanväki") in their practice. The power of the death and magic were at the very core of all their activities. This book presents the most important roles, spells, rituals and traditions of these sage-witches, as well as the most significant practitioners in history.
