"I can hardly abandon this city in its time of need." She licks her lips.

She's with her wife, obviously.

"Thank you. Hold your channel for now; I expect it'll be more useful later. In the meantime, focus on demons if you've got cold iron and cultists if you don't, or if your only cold iron is arrows. The Goddess chose a lot of paladins after the attack, we're not hurting for ways to pierce their hides. —Ser Seelah, use your discretion about how to allocate your Smite, assuming you still have it."

Wow it must be really bad, he thought She was almost completely broke. "I have a Weapons Against Evil but my mace is already cold iron."

Nod. "Anything else urgent that I should know?"

"We found some kind of report supposedly indicating the cultists' plans." She hands over the letter to Irabeth.

Camellia's doing a great job not making herself urgent. The plans thing sort of implies the report he'd have given about Hosilla. Wenduag's squared away. He has nothing to add.

Then Irabeth can lead them through the Gray Garrison! They quickly dispatch a group of cultists (Blai's spell does not think any of them are empowered), then head upstairs to a large balcony overlooking a courtyard.

On the balcony are two groups of cultists, who appear to have deliberately positioned themselves to be out of Detect Evil range from the entrance to the balcony, one blocking the path forward and one blocking the path to the left. The cultists are accompanied by a dretch and a pair of cambions, and slightly outnumber the crusaders.

One of the crusaders looks incredibly discomfited about something.

Would the crusader care to share with the class or should Blai just go dispatch the dretch?

"Think I know that guy," says the discomfited crusader, jerking his head towards one of the cultists. 

Across the battlefield, the cultist seems to be realizing the same thing. He holds up his hand to his allies.

This is almost certainly a horrible trap of some kind, but you can't just shoot people who might be attempting to parley because you think it's probably a trap. She signals to her people to hold their fire unless the other side's spellcasters try something funny. What does the cultist want to say?

"Hey! Good to see you! Wish we were meeting in different circumstances!" He laughs. "So, I'm going to be straight with you. The demons are going to win. Everyone fighting for the crusaders is going to die. In a month Golarion is going to belong to us. Or, you could switch sides, and we'll let you live, no sweat about whatever you've done as a crusader. Sound like a plan?"

His crusader friend glances nervously between the crusaders and the cultists. He's seen a lot of people die in the past day.

That's honestly better than she expected, which isn't saying much.

"We can arrest him and give him time to reconcile his soul, if he surrenders," Blai murmurs to the one on their own side. "I don't think his force can defeat ours even if you defect, do you?"

He looks at the demon force, then back at the crusaders. There are more of the cultists but he's not sure any of them can take Irabeth, and the crusaders are a lot more likely to heal people who get knocked unconscious but don't actually die.

He nods tightly at Blai. "Hail Iomedae!"

The demons are done waiting around for this loser to 'negotiate' with his 'friend.' They start shooting at the crusaders.

To arms, then. 

Quite. It's sort of heartening that the demons were able to wait that long.

This fight is much more difficult than the previous one; more of the cultists are spellcasters, and the cambions' arrows are deadlier and more painful than those of the human cultists. The demons and cultists don't really seem at all concerned with collateral damage, though that's a bit of a blessing in disguise — the dretch seems totally unconcerned with whether its Stinking Cloud impairs the cultists, and the clerics keep hitting their own allies with negative channels. 

Cultist negotiator doesn't exactly attempt to surrender per se, but when he's on his last legs he starts begging his friend to spare his life, and he hands over his weapon when Irabeth orders him to.

"Select Artigas, we need your channel... there, I think. Apfel, Tauner's at a bad angle, if he's still breathing hold him up so the channel can hit him."

Blai makes sure the surrendering cultist is secure, takes position, double-checks the radius, and channels.

Some of the unconscious crusaders get up. Four of them don't.

She surveys the situation.

"Ser Tauner, I don't suppose you've stopped feeling fear in the last five minutes?"

 "No, sir."

"Alright. You can stay here and guard the prisoner — what's your name?"

 "Landric."

"You can stay here and guard Landric."

Around the balcony, they can see the edge of the Wardstone, which seems to have impaled the building diagonally. Irabeth looks it over for a few moments, then leads the group around the corner to another door to another staircase.

Is Blai recasting his Detect Fiendish Presence?

Whenever he's got a Guidance up already and a calm moment yep.
