Glassback Grazers
Glassback grazers are herd animals whose translucent back plates cover living tissue that stores heat. They feed on producer mats, low browse, mineral films, and prepared tissues offered by the living ecologies along their routes. As primary consumers, they eat what those producers grow; as mobile heat banks, they carry warmth and share it within the herd.
Their plates also reveal much of what is happening inside them. Other organisms can use that information to care for a herd, bargain with it, or attack it. Staying fed and safe depends partly on managing who gets close enough to read.
What the Plates Reveal
The dorsal plates expose color, warmth, immune turbulence, reproductive readiness, fear, and signs of recent memory exchange. A skilled observer can identify a glassback’s last safe feeding place from the sheen on its back. Predators can read that history too, as can parasites, caretakers, children, and bored political enemies.
A healthy herd therefore gives observers information about the surrounding landscape and its relationships, as well as the animals themselves.
During the bright recovery phase after eclipse, glassbacks stand flank-to-flank in dense arrays. Heat passes between their plates. Low-grade memory gradients pass with it, sharing route confidence, dampening alarm, indicating hunger priority, and carrying herd affiliation.
Feeding and Traveling Together
Glassbacks must keep the cooperation of the organisms they feed on and travel among. They graze Prismwake Mats according to strict rules about how they bite. Feeding successfully means satisfying hunger while preserving access to the mat.
As they move, glassbacks disperse Burden Flowers and carry fungal spores between Candle Fungal Roads. Their readable bodies also give threadwings moving surfaces from which to gather information.
Herds often bargain with Sa’ueia family units, the small mobile groups through which Sa’auei’a organize family life and travel. The Sa’auei’a protect calving lanes, prune parasites, and read herd plate-states for signs of weather and danger. In return, glassbacks allow families to pass close by, carry lightweight goods, and lead them toward honest water.
What Shapes Their Behavior
Glassbacks need to feed without losing mat access, maintain the herd’s heat, and protect calves. They also work to preserve their reputation with the living routes they use and avoid predators capable of reading panic from their plates.
Their memory travels through several channels: heat gradients across the back, flank contact, gut symbionts, reports from burden flowers, and the taste of mats.
A herd is more likely to cooperate with someone who approaches calmly, removes parasites, rescues calves, or offers minerals. Keeping a respectful distance during plate exchange matters too.
Cooperation can break down when someone forcibly separates herd members, scrapes their plates, spreads panic, or overharvests the flowers they host. Reading a herd’s exposed state to arrange an ambush is another cause for refusal.
When threatened, glassbacks can darken their plates or produce false panic flares. They form tight rings around calves, refuse routes, and trample in coordination. They may deliberately flee through bitter mats to punish pursuers.
Portraying a Glassback
A glassback NPC should be social, sensitive to status, and readable enough for others to act on what they see. It should also be extremely aware of who is doing the reading. Access to its bodily information is a political concern.
Track the states that affect its choices:
- Herd trust: how much trust it has in those around it.
- Heat reserve: how much stored warmth remains.
- Calf risk: how threatened the calves are.
- Plate clarity: how clearly its plates can be read.
- Parasite load: how heavily it carries parasites.
- Route debt: what it owes the routes it depends on.
Show those choices through bodily actions. A glassback may expose or fog its plates, share heat, turn broadside, refuse to graze, flash a false alarm, or press calves into the center of the herd.
