Note 341 — Chapter XXVII · RELIGION.—SACRIFICES TO THE ALFAR, DISIR, FYLGJA, HAMINGJA, AND LANDVŒTTIR.
Reading edition
The nine women in black had been the Disir of the family, which was going to forsake the old belief; the Disir wanted to take with them the best member of the family before they left. Therefore they slew Thidrandi, whom the nine white Disir try in vain to defend. The nine white Disir were to be the guardian spirit of the family after it had adopted the new belief. From this we can see that the new religion could not entirely overthrow the old superstition and belief.
