我们在界限之外往回走，那是探险队的超时。

记忆中我们已经达成了巨大的成就，可是自豪却不曾笼罩着我们，阴雨的回环在这片本该安全的土地上流动，我们还能回去吗？

那个回程，那个小小的回程，我看到了血肉模糊的幻影，死亡的瞬间……

我真的看到了，那片记忆中回旋闪动的过往，它们不断重复，崩解有化身，从尘土中产生出新的某种自我，死去，然后再度死去——

我是不是也要被吸入这片循环了呢？吸入循环的我还是我吗？随着记忆闪动的，血腥而迷失的梦，那些未知的过往，都还在么？

他们，他们无助的惊慌失措，可是我们却无法看到那个失落的人，我们孤独的行走在层级的边缘……

你是谁，我是谁，我们都存在着吗？

他们只是上演着重复的戏码，而，无论何时，界限都在生长着；无论何时，回声都在上演着；无论何时，死神的脚步都越来越靠近你我……

我再也无法直视这片超界的土地了，我们疯了似的离开，然后疯了似的过去……

我们死了，我们都还活着，回声让我们几乎无法理解这片天空——

或许有人来过这里吧，或许他们只是死去了吧？

重复着的，无法改变的死亡瞬间——

那是一种折磨啊，那是一种——

我再也写不下去了，那场景里的一切都是恐怖的梦魇，仿佛下一秒就要变成血肉模糊的家。

现象编号 Cloud-95

等级 2

分类：持久性 全范围

区域：层级外围

形式：历史回响

描述：

Phenomenon Cloud-95，亦称“回声”，是一种于层级边缘区域被观测到的特殊现象。通常情况下，某一区域中“回声”的观测频率，与该区域受距离现象影响的强度呈正相关。

一旦Phenomenon Cloud-95在某个区域形成，其将持久存在，且不会随时间推移出现强度衰减或增强。唯一的例外是承载该Phenomenon Cloud-95的层级本身出现难以逆转的崩解。

Phenomenon Cloud-95在外观上呈现为一段在现象影响区域内反复循环播放的历史映像。该映像具有完整的视觉、听觉信息，其分辨率与真实环境无异。所呈现的历史片段可能从未被任何人类观测记录在案，但经交叉验证可确认其真实性，即该历史确实在时间线的某一节点发生过。

映像内部的“活物”¹会严格按照历史进程反复上演既定情节，直至该段历史对应的时间线行至终点。届时，所有活物会瞬时消散，并于同一历史的起始时间点处其各自所处的位置重新聚合，随即开始新一轮上演。该循环过程无任何间断或变体。

实验表明，Phenomenon Cloud-95无法因任何外界因素²而中断或改变其上演进程。同时，进入映像区域的流浪者无法与其中的活物进行任何形式的互动，例如：交流尝试无响应；触碰动作将直接穿过活物体而不产生任何反馈。然而，映像所呈现的环境场景具有真实的物理属性，能够对流浪者产生切实的影响。考虑到以上因素，及Phenomenon Cloud-95多发生于受距离现象影响的区域，，强烈不建议流浪者擅自进入尚未被完全探明的“回声”区域。任何流浪者或工作人员在进入前必须配备完整的环境防护装备及实时定位系统，且应避免对映像内活物产生任何依赖或试图改变历史进程的行为。

由于Phenomenon Cloud-95的特殊属性，其将被UNC4后室分部及云空探联作为重要的历史素材研究，此后对任意“回声”的进入尝试需在UNC4后室分部-回声研究分部的批准下进行。

“回声”-实验归档1

报告人员：UNC4-回声研究分部-[数据删除]
报告时间：2037年2月1日

---

实验内容：通过透镜聚焦某一回声内的光线，使其穿过一时空水晶。重复多次。
实验结果：投影特性正常，但显现画面由前厅聚落影像偏差为回声内某一人物的“过去”。这一“过去”通常与该人物某个执念有关。
实验结论：时空水晶的投影特性于回声场景内失常。

实验内容：通过■■■■■■引导Level Cloud-25内的“钛姆”粒子撞击一回声内的场景。
实验结果：场景未发生明显改变。
实验结论：回声内的场景不存在“过去”与“未来”，亦或是其随着时间推移不会出现显著变化。

“回声”-实验归档3

报告人员：UNC4-回声研究分部-[数据删除]
报告时间：2037年2月7日

---

实验内容：通过以脑髓液为介质的■■■■■■转移某一回声中的一小块场景。
实验结果：整个回声被转移到特定地点。
实验结论：回声中各个组成部分呈强关联性，在部分被转移后其余部分会立刻跟随；回声可以被使用特定手段转移至其它层级。

应对方式：

缓解：

• 不擅自进入回声
• 远离远方

加剧：

• 向远而行，直到终点
• 深入回声
