The Heart Shrinker
Cadmus O'Hare Faun II, along with vault dwelling friend Dr. Henry Helseth, creates The Heart Shrinker to pass time during a quiet day in the Doomsday Vault. The Heart Shrinker lives up to its name, shrinking hearts 10x smaller than the original size.
The box found its first use after the unfortunate suicide of Cadmus O'Hare, who abandons life after losing the game for captainship to Cada Blue, who defeats him in a game of Nostrovia. The Heart Lamp created with Cadmus O'Hare's heart now resides in the bunk of Helseth Arborium.
