====Main NPCs====

Main NPCs are the closest you’re ever going to get to playing a PC yourself. They have full character sheets just like a PC does, with five aspects, a full distribution of skills, and a selection of stunts. They are the most significant characters in your PCs’ lives, because they represent pivotal forces of opposition or allies of crucial importance. Because they have a full spread of aspects, they also offer the most nuanced options for interaction, and they have the most options to invoke and be compelled. Your primary antagonists in a scenario or arc should always be main NPCs, as should any NPCs who are the most vital pieces of your stories.

Because they have all the same things on their sheet as PCs do, main NPCs will require a lot more of your time and attention than other characters. How you one really depends on how much time you have—if you want, you can go through the whole character creation process and work out their whole backstory through phases, leaving only those slots for “Crossing Paths” open.

Of course, if you want, you can also upgrade one of your current supporting NPCs to a main using this method. This is great for when a supporting NPC has suddenly or gradually become a major fixture in the story. Players may fixate on a specific NPC, regardless of your original plans for them.

You could also do things more on the fly if you need to, creating a partial sheet of the aspects you know for sure, those skills you definitely need them to have, and any stunts you want. Then fill in the rest as you go. This is almost like making a supporting NPC, except you can add to the sheet during play.

Main NPCs will resist to the bitter end if need be, making the PCs work for every step.

Regarding skill levels, your main NPCs will come in one of two flavors—exact peers of the PCs who grow with them as the campaign progresses, or superiors to the PCs who remain static while the PCs grow to sufficient strength to oppose them. If it’s the former, just give them the exact same skill distribution the PCs currently have. If it’s the latter, give them enough skills to go at least two higher than whatever the current skill cap is for the game.
