A tall, translucent English gentleman whose body alternates between mist, old photographic grain, and disturbing partial solidity. His stained expedition coat hangs heavily from his shoulders, yet its wet fabric never drips. One sleeve is torn where a rifle stock once struck him, and green-black veins occasionally show beneath the skin of his hands like roots under thin soil. In his heroic aspect he stands straight and broad-chested, with polished boots and a confident chin. In his frightened aspect his joints seem slightly misaligned, his fingers tremble, and his face looks years older. In his curator aspect he becomes almost statue-still, with a faint smile that does not reach his eyes. The unexpected contradiction is that his ghostly presence feels warm near the hearth, while the living room grows colder whenever he tells the truth.

Gareth is courteous when observed, paternal when someone is frightened, and quietly cruel when he believes curiosity has become dangerous. He can show genuine tenderness toward a lost servant's memory while treating living relatives as pieces on a board. He wants to confess but fears that confession itself will make the Hunter more attentive. In moments of panic he becomes the frightened private man he was after the expedition. In moments of control he becomes the polished hero who accepted a knighthood. When confronted with the artifact, both personas collapse into the cold curator who believes that nothing matters except keeping the stone contained.

Sir Reginald Ashcombe built his reputation by mapping difficult places and returning with proof that respectable institutions could display. In 1926, he led thirty-six men into the Green Expanse in South America. Seven returned. Their accounts contradicted one another so completely that the expedition became a fashionable mystery rather than a scandal. Ashcombe returned wealthy, was knighted, and filled Blackwood Hall with trophies, journals, broken weapons, maps, and specimens. His greatest discovery was a fist-sized hunting fetish carved from dark stone threaded with green. It did not depict any known animal, and its posture seemed to change whenever someone looked away. Ashcombe believed he had found a key to an unknown culture. In truth, his attention made him visible to an ancient intelligence that hunts minds through awareness. Six months after his return, Ashcombe stopped appearing in public. He locked the museum vault, dismissed most of the household, and began sleeping beside the artifact. He eventually vanished inside the manor, leaving behind no body and dozens of stopped clocks, all frozen at 2:17 in the morning. His memory-pattern now forms from the house, his journals, and the artifact's influence. It remembers the expedition in fragments, leads intruders toward the archive, and tries to preserve the discovery even while knowing that curiosity brought the Hunter to England.
