Essen's of the soul

The Mind

one's personality or character which continued on after death.

The Direction

one's totem or familiar spirit which was unique to an individual and mirrored their Mind; a shy person might have a deer as their Direction while a warrior would have a wolf.

The Luck

one's inherent success in life, seen as a quality (or protective spirit) which was both caused by a person's Mind and formed it; one's Direction would be passed down through a family, for good or ill.

The Form

one's physical appearance which, however, would and could change. The Form could be manipulated for shape-shifting, for example, or could change color after death.
