The name Wangliang has hung in the old registers for thousands of years. Some texts call us essences of mountain and river; some, the pale remnant-souls of the dead; some say bluntly: creatures made of shadow.
The last comes closest. We live in shadows.
Not figuratively. To you a shadow is an absence of light. To us it is a territory — that thin film of dark that everything wears against the ground, and where film joins film, there run our roads. I step from your shadow into the tree's, from the tree's into the mountain's, soundless, traceless. In three hundred years my feet have not once touched the actual ridge of White-Bone Ridge.
Live in shadows, and you learn the rules of shadows.
A shadow is the most honest face a thing owns. A person can fake a smile; his shadow cannot — in a defeated man, the shadow's shoulders fall first. A person can lie; his shadow cannot — in a guilty man, the shadow leans away. The old wraiths handed down the trade-saying: skins may change a thousand ways; the shadow does not lie.
And one rule above all: the shadow follows the form, to the hair, to the instant. Raise your hand, and the shadow raises its hand in the same breath. This is a dead law of heaven and earth, firmer than sunrise — the shadow is the soul's print pressed onto the ground; while soul and body are one, shadow and form are one.
In three hundred years of reading shadows beyond count, I never saw that law broken.
The exceptions began last year.
First a carter on the post-road below the ridge. He cracked his whip — the whip fell — and only then did his shadow's whip-tip rise. Late by half a beat; aligned again within a blink; invisible unless you were staring. I assumed my eyes had slipped.
Then a clerk in a Bureau column. Then two porters in a caravan buying mountain goods. Then an itinerant physician lodging in the ruins of Bridgehead village.
All the same: the shadow, half a beat late.
I followed the physician three nights. By day he saw patients, made careful conversation — nothing to fault. But at night, when no one was near, he would stop. Simply stand in the middle of the road, motionless, for half a watch. The man not moving — and the shadow moving: flat against the earth, slowly, slowly shifting through postures, as if in conversation with something.
On the third night, the place where he stood was the fork that leads to the Eclipse Altar.
There is an old saying of my ancestors that I dug out of memory. Soul and body one, shadow follows form. But if soul and body are not one — if what rides in the body is not its original owner — the shadow balks. However perfect the newcomer's imitation, the shadow is the old soul's print. It cannot be re-cut. It can only be forced to copy — and however fast it copies, it runs half a beat late.
That late half-beat is the little of the original owner that never fully left.
The Sea-Overturning Yaksha spoke of replacements at the gate-foot. Old brother Shanxiao counted seven in and six out. The bone-eating ravens taste bones with the souls missing. Now I understand: the replaced are not in any register, not in any grave. They walk the open roads. They drink tea. They practice medicine. They sit for examinations.
There is exactly one way to recognize them: watch the shadow.
And in all the world, the only ones who can read shadows are we wangliang.
When the medicine-basket boy slept in the empty village, I put my head out of his shadow — don't be alarmed; that is how we say hello — and told him everything about the half-beat lag. He heard me out, and then asked the question no wangliang had ever thought to ask:
"Those half-beat shadows — do they themselves want to be recognized?"
I had no answer.
That same night I went back to the physician one more time. This time I watched not for lag, but for spirit. And do you know what I saw?
His shadow, against the ground, was writing — minutely, over and over — a single character. Writing it, wiping it, writing it again: like something held down by the head, and like something spending its last strength to leave one word of message.
The character was SAVE.
The shadow does not lie. The body is occupied — and the shadow is still crying for help.
So I travel west with the boy. My commission runs the length of the road: read the shadows. The half-beat-late ones — record them. The ones writing SAVE — record them above all.
Whether their bodies can ever be won back, I do not know.
But at the very least, someone must know that they are still there.
Even if all that remains of them is that thin film of dark on the ground — still fighting, still half a beat behind, still alive.
