这是古文明遗留下来的能量屏障，曾是维系生态平衡的最后防线。如今冰层开始龟裂，缝隙中时而释放出强烈能量波动，照亮整座夜岛。这座曾坚不可摧的结界正逐步瓦解，随之崩塌的，是整座岛屿的生命之脉。 What remains of the old civilization still pulses through Reyk. The Cryosphere was once a barrier of pure energy, the final mechanism preserving the island’s balance. Now, fractures run through the ice, and violent bursts of energy erupt through the cracks. The sky flashes with unnatural light. What was once indestructible is coming undone, and with it, the island’s fragile heartbeat.
