Could you explain more about the Sedir worker? I tried wiki and google, but only got stuff in turkish and a couple of resorts.
Seidhr, or spaecrafting, is one of the "magic"s of the Norse/Germanic cultures. The Sami, while having trading relations with the Norse and Germanic tribes, are no closer to them than the Celts were/are. A person skilled in seidhr was often called a voelva. It involves walking the nine worlds and interceeding with the ancestors and landvaettir. Jenny Blain, a modern athropologist, has done some work with seidhr from an anthro and personal angle; I highly recommend her book on the subject.
We know seidhr involved chanting or singing and some kind of herbs, either ingested or inhaled, and that the people who did it were considered wise and able to heal or harm. It is definitely different from the other form of Norse/Germanic "magic", which is runecraft. Also, voelvas travelled a lot; either there weren't many of them, or their continued presence lead to problems; a combination of both is possible.
Seidhr was traditionally considered female and runecrafting male, but most modern reconstructionalists I know don't mind the gender divide and go where the gods call them.
Seidhr is a form of shamanism in the anthropological sense, but not a form of shamanism in the religious sense.
That is, the word "shaman" as adopted by first nation explorers who analyze the cultures of other people is different from the word shaman as used in its original context and with respect by others who walk the paths, heal, and harm. Unless you're Tuvan, you
DAMN well better have a cultureal context for your use of the word "shaman", or - better yet - use the actual word from the culture you are working from.
