Roles

An individual's role within their House is determined by the House Area to which they are assigned. Each character is more skilled at some roles than others.

Codex
"Every adult member of a house is typically assigned to one of the house's areas. This is their role.

Each character has a skill level in each role, which contributes to the total score of a house in that area when they are assigned to that role. You can see the skill level a character has in each role by looking at their tooltip or by clicking on them.

Characters also have a natural aptitude for some roles. If a character has a talent in a particular role, their skill in that role will increase when they are assigned to it, and they will be happier at being assigned to it. You will learn the talents of house members over time by placing them in the relevant roles."
