Aquatic Fortress of Dirge (Boss)

**Syllis, the Gilded Echo of the Sunken Spire** **Origin:** When the Aquatic Fortress of Dirge first sank beneath the waves, the fortress’s Great Bell—cast from a singing alloy and tuned to the frequency of the tides—did not crack. Instead, it absorbed the collective grief of the drowning court and the crushing pressure of the deep. Over centuries, the bell's sonic resonance coalesced into a sentient entity of living vibration and saltwater, fusing the spirit of the fortress's last High Cantor with the metallic memory of the bell itself. **Lair:** The Resonance Chamber of the Lowermost Vault. Syllis dwells within the inverted dome of the fortress’s foundation, where the water is most pressurized and the architecture is carved from bioluminescent obsidian. It defends the "Heart-Tone," the original singing alloy core that maintains the structural integrity of the entire fortress.
