Rivals are NPCs who oppose the characters and make their presence felt whenever the characters are engaging in downtime. A rival might be a villain you have featured in past adventures or plan to use in the future. Rivals can also include good or neutral folk who are at odds with the characters, whether because they have opposing goals or they simply dislike one another. The cultist of Orcus whose plans the characters have foiled, the ambitious merchant prince who wants to rule the city with an iron fist, and the nosy high priest of Helm who is convinced the characters are up to no good are all examples of rivals.
A rival’s agenda changes over time. Though the characters engage in downtime only between adventures, their rivals rarely rest, continuing to spin plots and work against the characters even when the characters are off doing something else.
Goals. An effective rival has a clear reason for interfering with the characters’ lives. Think about what the rival wants, how and why the characters stand in the way, and how the conflict could be resolved. Ideally, a rival’s goal directly involves the characters or something they care about.
Assets. Think about the resources the rival can marshal. Does the character have enough money to pay bribes or to hire a small gang of mercenaries? Does the rival hold sway over any guilds, temples, or other groups? Make a list of the rival’s assets, and consider how they can be used.
Plans. The foundation of a rival’s presence in the campaign is the actions the rival takes or the events that occur as a result of that character’s goals. Each time you resolve one or more workweeks of downtime, pick one of the ways a rival’s plans might be advanced and introduce it into play.
Think about how a rival might operate in order to bring specific plans to fruition, and jot down three or four kinds of actions the rival might undertake. Some of these might be versions of the downtime activities described later in this section, but these are more often efforts that are specific to the rival.
A rival’s action might be a direct attack, such as an assassination attempt, that you play out during a session. Or it might be a background activity that you describe as altering the campaign in some way. For example, a rival who wants to increase the prestige of the temple of a war god might hold a festival with drink, food, and gladiatorial games. Even if the characters aren’t directly involved, the event becomes the talk of the town.
Some elements of a rival’s plans might involve events in the world that aren’t under the rival’s control. Whether such an event can be easily anticipated or not, the rival’s plans might include contingencies for taking advantage of such happenings.
