(Scientific Name: Cynodon aeolus | Common Nicknames: The Singing Carpet, Whisper Grass | Charles’s Ledger: Variable-F09)
Botanical Profile: The Singing Carpet
Habitat: Grows in thick, low-lying patches primarily in sheltered areas like ruined neighborhoods and abandoned parks.
The Fluted Blades: Each blade is curled into a hollow, flute-like channel and hardened with a high-calcium coating.
The Choir of the Wind: As air passes over the grass, it produces ethereal, whistle-like tones. Because blade lengths vary, a breeze creates a layered, harmonic chorus similar to distant wind chimes.
The Lullaby Effect: The soothing sounds act as a biological defense mechanism for the ecosystem, masking the sounds of approaching predators or the rustle of nearby Ghost Whips.
Charles’s Note: "The Chime Glades are alive with sound, not movement. Step wrong and it sings your mistakes, whispers them into the wind."
Physical Characteristics: The Hollow Sward
Calcium Armor: The blades are brittle compared to standard grass; they don't crush easily but instead "crack" or "snap" with a distinct percussive note when stepped on.
Muted Coloration: They appear as a muted green or pale yellow, blending perfectly with the dead organic matter (humus) of the forest floor.
Hollow Core: The hollow nature of the blades makes them incredibly lightweight and aerodynamic if detached.
Performance Specs: Material Science
Signal Mats: Survivors weave the sward into mats placed around camp perimeters. Any footstep on the mat creates a localized disruption in the harmonic "hum," acting as a precise intruder alarm.
Pipe Darts: The fluted blades are harvested to create high-velocity darts. Because they are hollow and rigid, they have less drag than wooden darts and fly with a signature "whirring" sound.
Acoustic Scouting: Experienced scouts can "read" the grass. A sudden shift in the pitch of the wind chimes usually indicates a large body (a predator) is displacing the air nearby.
The Singing Floor: Any creature moving through a Chime Glade at more than half-speed has Disadvantage on Stealth checks. If a creature fails a Stealth check, the "singing" of the grass alerts all predators within 100 feet to their exact location.
Lullaby Masking: While the wind is blowing (producing the Chime), all creatures have Advantage on Stealth checks to hide their own movement sounds, as the grass provides a natural "white noise" cover.
Signal Mat Alarm: A character with a passive Perception of 14 or higher can notice a change in the "hum" of a Signal Mat, granting them Advantage on Initiative rolls if an intruder approaches.
Pipe Dart Precision: Darts crafted from Chime blades have an increased effective range (+20 feet) and ignore penalties from light winds.
