Kalma’s folk means the dead living in graves. Finnish magicians have summoned the dead with spells to help them in difficult situations. In the spells, the dead are portrayed either as corpses in decay, covered in mold, or as skeleton-like figures. They are often portrayed as a family.
The underground world of the graveyards is called Kalma’s kingdom or Kalma’s mansions.
Didst thou come from Kalma’s kingdom,
From the castles of the death-land?
Haste thou back to thine own country,
To the Kalma-halls and castles,
To the fields with envy swollen,
Where contending armies perish.
Mages can summon their Nature from underground. A Nature is a person’s double, his guardian spirit, shadowy doppelganger, his counterpart in the world Beyond. The mage tells his Nature to rise from its grave, from underneath a tree or a rock. The Nature will rise wearing a hat and mittens in his hands, with brilliant eyes, spotted cheeks, hard as stone, tough as iron.
Arise, my Nature, reliantly, awake,
O Genius (haltia) of my life,
from under a tree, O Brilliant Eyes,
from under a flag, O Spotted Cheeks,
my Nature that is hard as stone,
my hair that is tough as iron.
