以下为一个围绕“救村庄”与“护送唯一线索”二选一的道德困境场景设计，并配套Stable Diffusion可用的提示词方案。内容分为：叙事氛围设定、核心分镜（抉择画面）、两个分支的独立画面、后果关卡视觉延续、参数与技巧建议。尽量使用能被多数前端识别的提示词结构，避免不兼容的语法，并保留可替换占位符以便你在项目中快速迭代。
一、叙事与氛围基调
当夜色像泼开的墨，边境村庄燃起潮湿的火，焦木与谷草的气味在冷风里拉出一条又一条刺鼻的线。你站在岔路口的石碑旁，雨点像细刃，在甲胄与披风上刻出密密的亮纹。左侧，村庄的火舌舔着屋檐，惊恐的人影在火幕前忽大忽小，如同被风甩动的剪纸；右侧，唯一线索携带者——一名面色苍白却眼神坚定的信使——抱着皮卷和玻璃匣中的微光符印，正踏向通往山隘的窄桥，远处的杀手剪影在雾中若隐若现。你知道这是二选一：救村庄，可能失去真相；护送线索，可能让火吞掉一个社区的未来。火光与月光在泥地上相撞，形成一条红蓝交界的湿亮刀锋——你的影子被一分为二。
二、核心分镜：抉择画面（用于海报或主KV）
用途：展示两难分岔，形成直观的红/蓝对置，作为关卡引导或开场动画关键帧。
正向提示词（SDXL推荐）：
dark fantasy, dramatic moral dilemma at a forked road, player character at the center back-view, cloak fluttering in cold rain, left side a village ablaze with thatched roofs collapsing, panicked silhouettes, sparks, embers, thick smoke; right side a moonlit mountain pass with a narrow wooden bridge, a lone courier holding a glowing sigil in a glass case and a leather scroll, assassins as distant silhouettes in fog; cinematic lighting, dual color contrast (warm fire orange vs cold moon cyan), wet ground reflecting red-blue light, heavy clouds, wind, rain streaks, volumetric fog, high detail, AAA game key art, dynamic composition, 32mm lens, low angle, strong rim light, sharp focus on silhouette readability, tense atmosphere, epic scale, environmental storytelling
负向提示词：
blurry, lowres, watermark, logo, text, caption, oversaturated, flat lighting, extra limbs, deformed hands, bad anatomy, incoherent perspective, jpeg artifacts, messy composition
参数建议：
- 模型：SDXL系（如SDXL 1.0衍生）或等价高分辨率模型
- 尺寸：1536x864 或 1280x704（横版海报）；CFG 6–8；步数 25–40；采样器如DPM++ 2M Karras
- 说明：保持单个主体轮廓清晰，使用双光源色温对比强化抉择
三、分支A：拯救村庄（动作高强度、火场叙事）
画面1（近景行动）：主角冲入火场，托举倒塌横梁，火光映得汗水与雨水在面颊交织。背景可见抱孩的母亲、翻倒的水桶、倒塌半壁的屋脊。
正向提示词：
hero rescues villagers from burning village, collapsing thatch and wooden beams, roaring fire, flying embers, buckets of water splashing, frightened mother holding child, goats scattering, smoke layering, sparks bokeh, sweat and rain on armor, intense motion blur on debris, cinematic orange glow, practical firelight, high detail, mid-shot, 50mm lens, dynamic pose, dramatic rim light, wet textures, volumetric smoke, environmental storytelling
负向提示词：
low detail, flat fire, plastic-looking flames, extra fingers, melted faces, messy background, text, watermark
画面2（余烬后的静）：清晨的灰烬里，幸存者围在焦黑的井栏旁，小孩子抚摸被烟熏黑的玩具。色调低饱和，残火吐出最后一缕温度。
正向提示词：
post-fire dawn, ash-covered village square, exhausted survivors, charred well, smoldering beams, pale sunlight through smoke, muted palette, soft fog, quiet grief, subtle god rays, environmental storytelling, 35mm lens, subdued mood
四、分支B：护送唯一线索（悬疑潜行、冷色叙事）
画面1（桥上对峙）：在窄桥中段，主角护在信使前，远处黑影在雾中拉弓；玻璃匣中的符印投出微蓝的图纹，在主角护臂上流动。
正向提示词：
escort the only clue across a narrow wooden bridge, moonlit pass, blue glow from a sigil inside a glass case, courier protected behind the hero, assassins in fog aiming arrows, taut bowstrings, wind-blown cloak, rain streaks, cold palette cyan-blue, high tension, cinematic contrast, shallow depth of field on hero and courier, crisp raindrops, 85mm lens portrait action, strong silhouette readability
负向提示词：
noisy fog, flat contrast, muddy colors, extra limbs, crooked weapons, lowres, watermark
画面2（山隘安全屋）：石室中，信使展开皮卷，符印投影在墙壁形成一张古旧地图与公式，主角侧面神情冷峻，火盆的暖光与符印的冷光混合，映出复杂的蓝金色。
正向提示词：
mountain safehouse interior, stone walls, brazier warm light mixing with blue sigil projection, ancient map and equations floating, courier unsealing scroll, hero profile stern, mixed lighting (warm+cool), particles in air, high detail, 35mm lens, focused, mystical yet grounded
五、后果关卡视觉延续（强调抉择带来的长期图像叙事）
A后果（救村庄—失线索）：地图上更多地区被疫斑符号蔓延，村庄虽重建却显迟缓乐观，玩家面对不断扩散的阴影情报。
正向提示词：
campaign map table, ink spreading like disease across regions, worried council, rebuilt village miniature with scaffolding, candlelight, parchment texture, selective focus on spreading stain, muted warm tones, narrative tension
B后果（护送线索—村毁）：归来时只剩焦土与风中挂着的半面祈愿布，空旷的操场上留着被烧裂的木马。远景里乌鸦盘旋，画面冷硬，地面泛蓝的月光像冷铁。
正向提示词：
ruined village at night, scorched ground, half-burnt prayer ribbons fluttering, cracked wooden horse, scattered pottery, crows circling, stark moonlight, cold palette, desolate, high detail, 28mm wide shot, long shadows, emotional weight
六、抉择画面（双联或分割构图）技巧
- 颜色对置：左侧暖（火橙/金），右侧冷（蓝/青）。在地面加反射，以湿地镜面统一画面。
- 光源分离：使用“dual lighting, warm key light vs cold rim light, split color grading”强化两难。
- 构图建议：三分法把主角置于中央偏下，左上火、右上月，地面反射作为视觉引导线。
- 镜头与焦段：32mm-35mm适合环境+人物的关键帧；85mm适合桥上对峙的人物张力。
七、Stable Diffusion提示词写作要点与权重
- 结构顺序：主体与动作 > 场景与时间 > 光影与天气 > 构图与镜头 > 质感与风格 > 情绪词。
- 权重强调：在多数前端中，圆括号可增强词语权重；也可使用(keyword:1.2)形式进行精确加权。建议对“fire, rain, glowing sigil, assassins silhouette, dual color contrast”等核心锚点做轻度强调以避免模型忽略关键元素。
- 负向提示词：控制解剖错误、重复肢体、过度压缩痕迹、标志水印等常见瑕疵。
- 一致性：为主角建立LoRA或将其外观关键词固定（发色/盔甲/披风颜色/武器形制），并固定seed在不同分镜间重用；用ControlNet-Depth或Pose保持姿态与构图。
八、参数与流程建议（通用）
- 分辨率：关键帧横图 1280x720–1536x864；近景人像可用1024x1280竖图；地图与大场面用更宽的横幅。
- 采样与步数：DPM++ 2M Karras 或同类稳定采样器，步数 25–40；CFG 6–8。需要更强细节时可先中分辨率生成后以高分辨率修复（hires fix 或图生图）。
- 图生图迭代：先用低CFG锁定叙事构图，再逐步提高CFG与细节。火与雾容易互相吞噬，可分两次生成（先结构，后加雾/火特效）或用局部重绘上火花与雨迹。
- 调色与材质：用“cinematic lighting, volumetric fog, wet ground reflections, particles, sparks bokeh”等词控制氛围层次；避免“oversaturated”以免两侧色温冲突失衡。
九、可复用模板（占位符可替换）
模板A（抉择总览）：
[dark fantasy moral dilemma], hero at a forked road under rain, left: burning village with panicked silhouettes and collapsing thatch, right: moonlit pass with a lone courier holding a glowing sigil in a glass case and a leather scroll, assassins in distant fog, dual color contrast (warm fire orange vs cold moon cyan), wet ground reflections, dramatic rim light, volumetric smoke and rain, cinematic composition, 32mm lens, AAA key art, high detail, tense atmosphere
负向：blurry, lowres, text, watermark, extra limbs, bad anatomy, flat lighting, oversaturated
模板B（救村庄动作近景）：
hero lifting a collapsing beam to save villagers, roaring fire, flying embers, sweat and rain on armor, terrified mother and child, buckets splashing, dynamic motion, warm firelight, orange glow, smoke layers, 50mm lens, high detail
负向同上
模板C（护送线索桥上对峙）：
escort scene on a narrow wooden bridge, hero shielding a courier, glowing blue sigil in glass case, assassins aiming from fog, rain streaks, cold palette, shallow DOF, strong silhouettes, 85mm lens, cinematic tension
负向同上
十、微调与故障排除
- 火场过曝：加入“controlled exposure, detailed flames, textured smoke, balanced highlights”，并降低饱和度词。
- 雾吃掉细节：减少“heavy fog”强度，改用“light volumetric fog, edge contrast preserved”。
- 人群消失：明确“panicked silhouettes of villagers, multiple figures, varied poses”并提高步数。
- 手部与武器畸形：加入“clean hands, correct anatomy, proper grip, detailed weapon design”，必要时用局部重绘修复。
以上方案在视觉上把“救村庄”与“护送唯一线索”的抉择撕裂成两股可以触摸的风：一股炽热、带着焦糖与烟灰的甘苦；一股寒凉、夹着铁与雨的紧绷。用色温与光影的拉扯、材质的湿与干、空间的拥挤与空旷，去呈现一个玩家必须承担后果的瞬间，并通过一组可扩展的提示词将这种道德重量稳定地落在画面里。祝创作顺利。
