Dragon Bloodlines and the Serpent Seed by Robert Sepehr

The Druids were said to believe that the soul was immortal and passed at death from one person into another.

Roman writers also stated that the Druids offered human sacrifices for those who were gravely sick or in danger of death in battle. Huge wickerwork images were filled with living men and then burned; although the Druids preferred to sacrifice criminals, they would choose innocent victims if necessary.
