The Temple Between kicks off with the party going to see Lavinya in the Temple of Erathis in the Divine Knot in Nine Bells. Her main conern is her friend, Haelyn, who's the caretaker of the shrine of Erathis in Tradetown. She also mentions that the senior clerics in Overlook have all been behaving slightly strangely. She doesn't mention any reward for services rendered.
While Gunpowder doesn't mind asking around about Haelyn, he isn't going to put out for free, and takes the view that poking senior clerics with a stick is probably a bad idea. (Well, you wouldn't do the same to the Archbishop of Canterbury or the Pope, would you? In fact, you wouldn't get much within five metres of them at the best of times.) This is a cash-for-questions gig rather than free-to-air service paid for by the licence fee.
When I was writing up The Siege of Bordrin's Watch, I found that Overlook takes up a seriously large chunk of real estate. I measured it out on the area map to put it into perspective and found that the dot on the map does the city a disservice. The place is a sprawl across the landscape.
But the size of Overlook had me wondering how far it was between the Divine Knot and the shrine of Erathis in Tradetown, and how long it'd take the company to get between one and the other. The distance is roughly 3.8 miles (6.1km) mainly because the walls within the city only have two ways in or out, which forces everyone to travel around the perimeter. Assuming that the adventurers walk at an average speed of about 1.2+ m/sec, the journey is going to take them nearly an hour and a half. I estimated that in the course of the day, the PCs spent about four and a half to five hours just walking around Overlook.
When the party encountered Grovald in the shrine of Erathis, I decided that they ought to capture him. I also had Gunpowder hating Grovald and deciding to throw the Geneva Convention out of the window for his interrogation after the fight.
For some reason, I made Gunpowder (now in his sixth year of existence, I find) a paladin of Helm (although I suppose I should switch his allegiance to Torm or, better for the Scales of War, Bahamut), which has mostly meant nothing. Gunpowder occasionally comes out with "By Helm's tumescent boy parts!", but I've never really characterised him in terms of what it means to be a follower of the god. The 3.5e FR Campaign Guide says
Helm is an unflinching and dedicated deity. He is often viewed as emotionless and unconcerned with moral issues in the face of duty.
In other words, the end justifies the means.
I used this as an excuse for Gunpowder to threaten to employ some ultraviolence to get Grovald to talk.
In this part of the adventure, poking various priests with a stick actually achieves next to nothing. At one stage, the PCs are meant to view a failure to sweep up in the corners of one temple as evidence of something being badly wrong. Ludicrous.
The most effective starting point is the investigation of Haelyn's disappearance, which points them in the direction of Durkik, the High Ancestor of the Temple of Moradin, and introduces the mysterious General Zithiruun. The ambush in the alley (which I've yet to deal with) points the party towards another dodgy customer, who is a better lead to the warehouse than Durkik, who is merely a bit tetchy when the PCs encounter him.
Since the visit to the Pig and Bucket is another night time venture (like the encounter with Grovald), I suppose I can send the company off to Stone Anvil or the Temple of Moradin in the Divine Knot to fill in their day; or Gunpowder and Glory can spend the rest of the day having a lot of sex, and Power can do the same with his girlfriend, Gurdis, in her office at the university – again.
