The builder is the first character role that should be assigned, as these are the characters that perform all construction tasks, such as building new rooms or furniture.
Builders who are constructing an enclosed room will often complete the construction only to find themselves imprisoned within the room. If the room is oxygenated or you are building on to a preexisting room, you may forget to remove the dividing wall between the two sections. If this occurs, your Builder will remain trapped in the room, suffering in silence, until they ultimately starve to death.
