The Viceroy represents the Ruler’s interests on an ongoing basis in a specific location such as a colony or vassal state (see the optional Vassalage edict on page 233). The Viceroy is in effect the Ruler for that territory; her orders are superceded only by direct commands from the Ruler.
Benefit: Add half your Intelligence or Wisdom modifier to Economy. You may assume any leadership role (including Ruler) for your colony or vassal state, but any benefit you provide in this role is 1 less than normal; if you do so, you must spend 7 days that month performing duties appropriate to that leadership role in addition to the 7 days spent for Viceroy duties.
Vacancy Penalty: If you have no Viceroy for your vassal state, treat it as if it had the Ruler vacancy penalty.
