Seekers are a special class of shamans who track and rebalance the souls of those who stray from the Lighted Path. They are few in number and reclusive, with only two still living in the world at this time. The others are long dead and chose to remain behind and provide this service.
They are extremely powerful figures. They must be- the predators of the spirit world devour souls and to slip once means permanent oblivion. What happens to those whose souls are devoured is unknown.
