I am loving the whole War of the Burning I have made Torrent "go elsewhere to get information or negotiate" for several scenes during the first half of adventure one, but I can't imagine how to do this with her (AND Crystin AND Haddin) during adventures two and three...
AM, I'm running the 3.5 version of the game, just finished
Scouring, and have just started
Indomitable. I have run into similar NPC-laden situations. They weren't hard to manage, and didn't hamper the game.
I handled Torrent in the first adventure as sort of a Resistance 'big wig'. It was her job to recruit the party for the snatch n' grab / courier gig... but not much else. I used her in the first few encounters (since she was still present), but very little after that.
I even had her stay in Gate Pass after when the party made good their escape (citing responsibilities to the city under siege).
Crystin and Haddin pose another problem. As it's likely that any party worth their salt will try to lug these two through the Indomitable Fire Forest. I've seen many of the posts here on the boards say that outright murder was the solution for Haddin, but I'm not sure the players I'm with will make that leap... at least until I force the issue with Haddin's dirty tricks.
At best, I expect them to run him off... not kill him.
To force the point, I've already had him charm the party's mage (into keeping quiet after he had determined that Crystin was under some sort of magical compulsion). Eventually, that will come back to bite Haddin I'm sure.
I've also decided that Haddin will be a vocal supporter of Kazyk's offer, as he would be the most likely to make a bargain with the devil. That's sure to strain his welcome in the party (they really are a bunch of do-gooders).
Crystin is another story, entirely. I am using psionics in the 3.5 game, so, rather than keep her as a sorcerer... I have statted her as a psion (seer).
But a character level does not an adventurer make.
In my game, she is still largely a scared and ineffective combatant. Sure, she'll get glimpses of the future when it's dramatically appropriate, but she will be the damsel in distress for the better part of
Indomitable. When (if) she and her father make it to Seaquen... they will settle into whatever sort of life awaits them there (now that being said, I'm absolutely positive that Haddin's treacherous ways will not go unaddressed for the entire adventure... so sometime during the fire forest, I expect things to come to a head).
