Household Corruption is a cumulative score reflecting the environment of your home. :

The Master draws from three interconnected wells:

: A collective stat for the player’s manor, influenced by the residents' combined corruption levels.

: This is the sum of all members' corruption. High household levels can cause hygiene to drop and may slowly corrupt children living in the home. Conversely, having children under 13 or slaves with the "Pure" trait drastically lowers this value.

: High corruption on key characters like Aria can change the outcome of end-day political events, leading to more depraved societal shifts. Political Events - Masters of Raana

In Master of Raana, Corruption represents the shift from "civilized" or "moral" behavior toward depravity, dominance, and the loss of empathy. It is not just a flavor stat; it actively changes how you interact with the world and how NPCs perceive you.
