Yan is the sigil of Wisdom. To study Yan is to seek the wisdom of the ancients and knowledge from the past. Father of all, Yan’s sphere of influence, covers meanings from enlightenment to caution.
Yan is composed of a twice bent bar struck through by a large bar. This represents the past and the present unchanging and the knowledge and wisdom that comes from age.
As a Warrior Stone, Yan either has the vertical line replaced, or the north and south ends are in use. As a Booster Stone, Yan will be either on top of the base sigil, or even inside it.
