Hey, there. I've been jonesing for a playthrough of NWN1's main campaigns with all (or some) of the henchmen in my party at once. No mods or console commands have made this possible, so far.

Still, I'm hoping it could be possible. Does anybody know a way to edit the modules to allow this? Thanks very much! :)

OldMansBeard's OHS Henchman System allows you to make your own party. As far as I know, it doesn't allow you to use alt he NWN henchmen, but you could always create them yourself and use them that way (won't get you their quests though). Not exactly what you're looking for, but it does give you the opportunity of playing with a larger party.

Firstly, I recognize that you have probably moved on from this long since.
However, there is an editor named Leto ( and [url=https://neverwintervault.org/project/nwn1/other/leto-prc-version]PRC versions are available) which allows you to convert NPCs tp PCs. You can use it to convert the henchmen from NWN's original campaign to PCs in your local vault. Then if you have OHS loaded, you can save them to the OHS list of henchmen. I don't think this would allow/support their quests but it will allow a fairly large party which includes them as henchmen.
