Aethelgard

深冰蠕虫（Cryofagus profundus），通称霜噬，是一种盲态、蠕形生物，繁衍生息于埃塞尔加德低温地壳深处的冰川裂隙中。这种滤食者通过摄取悬浮于冰下暗流中的放射性尘埃颗粒维持生命，将辐射转化为代谢能量；同时，因其完全缺乏眼睛与色素组织，对视觉捕食者而言几乎不可察觉。 尽管栖息于接近绝对零度的环境，霜噬的代谢核心仍会散发微弱的热信号，形成局部热羽流，可被红外传感器探测到。这一非本意的信标却悖论性地成为霓虹行者（Neon Strider）的主要诱饵，使得这条原本隐蔽的蠕虫在热异常罕见且备受渴求的生态系统中极易被捕食。

Tenebrus radiophila forms expansive, charcoal-black mats clinging to the leeward shields of basalt outcrops on Aethelgard's frozen plains. These flat colonies bypass photosynthesis entirely; instead, specialized pigments in their upper cortex directly harvest high-energy ultraviolet radiation, converting it into chemical bonds within hours. The resulting biomass glows with a faint, violet bioluminescence only when shielded from the star's harsh glare. In this cryogenic wasteland, Umbra-Moss remains the sole primary producer, anchoring the local food web. Its dense, heat-retaining layers create micro-habitats where scavengers burrow for warmth and sustenance. Without these dark, radiating islands of life, Aethelgard's surface would remain a sterile expanse of ice, devoid of organic carbon or movement.

静滞漂流者（*Electroplasma vagans*）永恒悬浮于埃塞尔加德电离的上层大气中，其半透明、水母般的伞盖随着捕获的紫色闪电而搏动。特化的纤毛过滤来自星球无尽紫外线风暴的环境静电，将大气电荷转化为代谢能量，使该生物在有毒云层之上失重漂浮。 当电能储备耗尽时，这些漂流者会穿过低温雾气降落到地表， scavenging 霜颚兽的尸体。它们的静电场短暂融化附近的冰层，使柔韧的触须得以从干枯的残骸中提取富含营养的液体，随后再次升入风暴肆虐的天顶。
