Carnal Instinct Key (OFFICIAL — HANDBOOK)

Let me start by checking if "Carnal Instinct Key" is a known item in any popular games. Let's think of games that have keys as key items. There's Metroid with its Power Bombs, The Legend of Zelda with keys for dungeons, or maybe Dead Space with items like the Keycard. But "Carnal Instinct" sounds a bit more... adult-themed. Could it be from a horror or thriller game? Or maybe a narrative-driven game where the key is symbolic?
