五位核心人物的双语小传，以及他们各自的五行与十神对位。五行给方向，不判命；十神看气质，不看善恶。
Bilingual bios of the five core characters, mapped to their Five Elements and Ten Gods. Elements give direction, not verdicts; Ten Gods reveal temperament, not morality.
街巷出身的贼。金棕色碎发、深绿的眼睛——狼血在他体内沉睡，红月升起时便躁动。他偷东西，不偷命；可他从旧宅铁箱里偷出的那柄缠蛇之剑，是一笔「债」——迟早要还。
A back-alley thief with chestnut hair and green eyes. Wolf blood sleeps in him and stirs when the red moon rises. He steals things, not lives — but the serpent-wrapped sword he lifted from an iron chest is a debt that will come due.
战场上的军医，精灵血脉。随身带着追魂花——花能追回将散的魂，却救不回已许的诺言。她救人，也毒舌骂人；她的救赎之路，从红月下的精灵血开始。
A battlefield healer of elf blood. She carries soul-chasing flowers that can call back a fading soul — yet they cannot undo a promise made. She saves people and scolds them, too; her road of redemption begins with elf blood under the red moon.
镜殿中的法师，来自深渊。一百年前被亏欠，他便在镜子里等了一百年。他执掌钥匙与镜子——镜子是禁锢，也是自我认知；他是被困者，也是守门人。
A mage of the mirror hall, born of the abyss. Owed a hundred years ago, he has waited inside the mirror ever since. He holds the keys and the mirrors — the mirror imprisons, and it reflects; he is both prisoner and gatekeeper.
流浪的人类，土一样的沉与稳。他为寻妹而走，也愿为承诺献祭；他信合作胜过孤胆——深渊之门，要三人合一才能封住。
A wandering human, steady as earth. He walks to find his sister and would give himself for a promise; he trusts alliance over lone courage — the gate of the abyss closes only when three work as one.
凯流浪寻妹的终点。剧本设定她与凯的血缘牵系，贯穿「献祭」之线；她的具体行止，以正式分集正文为准。
The sister Kai wanders to find. The script ties her blood-bond with Kai through the line of sacrifice; her full story follows the published episodes.
