A mud-stained field account identifying the Briarback Matriarch, the Root-Hollow she guards, and the warnings crews ignored before fighting her.
A mature briarback settles over a Root-Hollow and remains there. Decades of growth make the animal low, broad, and difficult to move. Thorn plating thickens across its back. Old breaks remain visible beneath new layers. A large matriarch may carry tool marks, animal scars, and pieces of failed traps without any of them being recent.
The Briarback Matriarch in Greenveil has occupied the oldest known Hollow since before the abandoned survey roads were cut. No reliable track shows her leaving it. Crews who describe her as roaming have usually mistaken a younger briarback for the same animal. The Matriarch does not need a hunting range. Her food, nest, and brood ground are within the roots beneath her.
The ground gives warning before she strikes. Fine roots tighten near the surface. Loose water draws toward the Hollow instead of downhill. Thorn tips rise through the soil in a widening boundary. Anyone who crosses that boundary should expect a direct territorial attack. She may call other Greenveil defenders when injured, but she does not pursue a retreat beyond the nesting ground.
Survey crews made three documented attempts to clear the Hollow. The first used noise and smoke. The second cut an approach through the roots. The third set hauling gear into the roadbed and tried to pull the Matriarch free. All three attempts failed. The surviving reports describe stronger root movement after each attempt. None records what the survey expected to find underneath.
A Root-Hollow is not an ordinary den. Water, seed, shed growth, and old harmonic residue collect there. Greenveil field readers use Hollows to compare changes in the forest over long periods. Briarbacks have guarded them for so many generations that removing the animal may also damage the record the crews came to study.
This does not make the Matriarch harmless. A party entering the Hollow is entering ground she will defend with enough force to kill them. It does establish the useful fact that she is guarding a fixed place rather than searching for victims. Mark the warning boundary. Keep the retreat open. Do not call a territorial animal wicked because somebody placed an expedition objective on top of its nest.
