Sky-Tide Crownwhale
The 18-meter adult is non-aggressive. It filters food from the wetland and uses enormous hollow crown antlers to emit a low-frequency song that gathers multiple species for migration along the ancient tidal channel.

Habitat and Mechanism
The ancient tidal channel at the old tide station within Tidal Echo Wetland。Warm, humid dome exhaust, seawater intrusion, pressure release from old tide gates, and submerged metal structures form a resonant wetland. The creature's low-frequency song travels through that water system and coordinates migration along the ancient channel.
Enter Tidal Echo Wetland ↗Behavior and Ecological Role
The 18-meter adult is non-aggressive. It filters food from the wetland and uses enormous hollow crown antlers to emit a low-frequency song that gathers multiple species for migration along the ancient tidal channel.
Its passage was the week's central finding. Fang confirmed that it showed no intent to attack, and K reopened the ancient channel so it and the other migrating species could pass. Its echo then stabilized the wetland's water system.
Form and Identification
One migrating adult recorded this week; family groups with calves may remain offshore
- Broad, streamlined whale-like torso measuring about 18 meters
- Four short, massive pillar-like legs for semiaquatic movement
- Enormous hollow crown antlers of pale nacre and salt crystal
- Gentle dark eyes and faint cyan throat pleats
- Low-frequency ripples that draw multiple species toward the migration route
Observation Rule
They did not treat a divine-class animal as an enemy. Fang synchronized through BCI to assess its intent while K manually reopened the old gate, giving the animal and the wetland a route instead of forcing an encounter.
Fang and K detected the animal through low-frequency patterns on the water and observed it from the side of an elevated structure.
