Character from Primal Hunter by Zogarth
Jake's oldest friend turned undead trap-master — a man who became Risen to save his girlfriend's soul and now builds dungeons that would make gods nervous.
Casper was Jake's friend before the System, which means he knew Jake when Jake was just a depressed office worker — not the apex predator he became. That history gives him a unique perspective: he's one of the few people who can call Jake on his bullshit without getting the Gaze of the Apex Predator turned on him. His girlfriend Lyra died and became a Blightwraith — her soul is stored in a legendary necklace he wears. Everything Casper does is oriented around eventually restoring her fully. He became Risen himself to understand undeath from the inside. His trap-making and dungeon architecture skills are recognized at the divine level — Minaga personally acknowledged his talent, which is the equivalent of a master chef complimenting your seasoning.
Ashen skin, grey eyes with black pupils, and black hair that's graying despite his young age — the physical markers of his transformation into a Risen. His expression carries a permanent weariness that predates his undeath. The air around him feels colder, and shadows gather at his feet without being asked.
