Introducing monsters

Whenever it's time to make a GM move, you can introduce a danger and put a monster in the scene.

Don't worry about your monsters being "fair fights" or "balanced encounters" or something that the PCs can even defeat. Worry about your monsters making sense. Portray a rich and mysterious world, right? If it makes sense for the PCs to stumble across a pair of (extremely dangerous) thunder drakes, go for it. Then play to find out what happens.

Exactly how you introduce a monster will depend on the situation, the monster's tags and qualities and moves, and the actions of the PCs. "Obvious" monsters encountered in a wide-open space will give the PCs plenty of opportunity to plan and react. Stealthy monsters in a dark, cluttered space while the PCs stumble around in torchlight? Not so much.

The PCs are up in Gordin's Delve trying to trade off some valuables they found in the Green Lord's tomb. Rhianna's off talking to a contact. Vahid, Caradoc, and Blodwen are at a pub. Caradoc and Blodwen get up to leave and Vahid, he sees a couple of unsavory types get up and follow.

Now, if these guys are just a pair of local miners that Caradoc managed to tick off, then I'll introduce a danger and let the PCs see them coming. "About halfway back to your hostel, you realize that you're being followed. It's those guys from the pub and they look pissed. What do you do?" The PCs have all sorts of options—they might try to lose them, or set an ambush, or talk, or whatever.

But if these bad guys are stealthy cutthroats who regularly murder unwary travelers in alleys and loot their corpses, then I'll be much more aggressive about it. I'll start by hinting at more than meets the eye. "You find yourselves in a dark, empty little trash-strewn square, and everything's quiet. Too quiet. You feel like you're being watched. What do you do?"

Let's say they Seek Insight, roll a 7-9, and ask, "What should I be on the lookout for?" I'd say, "You're pretty sure someone's following you, or maybe circling ahead. And these alleys are filled with good spots for an ambush. What do you do?" Whatever it is, they'll be on guard. My next move will probably be to introduce a danger, but softly and with a chance to react. "As you pass a dark side-alley, two thugs rush out towards you, what do you do?"

But suppose they Seek Insight and get a 6-, or just ignore my veiled threat and blunder on. In that case, I'll introduce a danger hard and painfully. "Caradoc, this guy comes out of a dark side-alley and snags your right arm, twists, and shoves you face-first into a wall. Take 1d8 damage. Blodwen, you see a second guy step forward, sneering, a glint of metal in his hand. What do you do?"
