Dr. Felix Amarinth

Dr. Felix Amarinth, a neurobiologist and known radical within the early post-Fall enclave of Threshold. He discovered and named the Lumen Leeches in 69 SE during a failed expedition to retrieve pre-Fall pharmacological archives.
His journal, “The Pulsing Mind,” is still preserved in the New Medical Library, though many of its pages are sealed due to doctrinal concerns.

Dr. Felix Amarinth first encountered the Lumen Leeches deep within the Drowned Trenches, during a perilous expedition in 69 SE to recover lost neurochemical treatment archives from a submerged pre-Fall wellness facility. The ruins were choked with fungal rot and bioluminescent detritus, but it was the soft, pulsing light in the water that drew his attention—worms clinging to rusted rebar, gliding through mineral-rich pools, clustering around the corpses of drowned researchers long since claimed by time. He collected specimens obsessively, intrigued by their synesthetic glow patterns and their uncanny ability to soothe his nightmares after each contact. Naming them Neuroglow siphonophora, he brought them back to his lab, convinced they were the key to treating the psychic trauma of post-Fall humanity.

But over the following months, his colleagues began to notice his behavior shift. He slept less, spoke in whispers, and seemed always surrounded by the dim flicker of leeches coiled around his arms, neck, and even his face. His notes became erratic—half poetic, half unreadable. He claimed the leeches were not just regulators but interpreters, allowing him to dream with clarity and commune with deeper patterns of thought. By the time the Doctors sent a retrieval team, his lab was empty save for glowing water tanks and fragments of his journal—The Pulsing Mind—pages still damp and trembling with mucus. Some say he fled into the flooded ruins to join the original leech flock. Others whisper he never left Camp Hope, only now wears different skin.
