Thurgun was taught to be a Shaman by his India-Indian parents, who came 
from a modified Hindu tradition that emphasized Reincarnation.  They 
believe that when you die, you pass through the Astral Plane before being 
reincarnated, and that you leave behind an 'echo' of that past life.  If 
you ar particularly tuned into the Astral world, you can summon your own 
past-life echoes as Spirits of Man.

Instead of taking on an aspect of an animal Totem when performing magic, 
they instead take on an aspect either of a past incarnation (particularly 
likely when summoning an echo of that incarnation), or of a skeleton or 
mummified body.

Advantages:  +2 dice for Health spells, +2 dice for Spirits of Man
Disadvantage:  Thurgun can perform a ritual for the dead that hastens
their soul's trip through the Astral plane to reincarnation, and ensures
that the echo they leave behind is more whole and intact than usually 
happens.  When someone dies in his presence, he will want to perform this 
ritual for them.  Should Thurgun himself kill someone, he *must* perform 
this ritual, or lose his bonus dice (above) until he does so.  (Though 
this loss of bonuses does not prevent him (as a Shamanic mage) from 
casting these spells or summoning those spirits at all.)

(The ritual is an exclusive complex action, and he has to use a special
expendable fetish in the ritual.)
