This is the primary component of the mod. Note that, in order to gain a stronghold for an NPC, you need to have that NPC in your party when you do the quest that leads to the strongholds.
Yes, that does mean you can only get a stronghold for Imoen if you side with the Shadow Thieves and do the quest Renal Bloodscalp gives you in Chapter Six.
You should also have the cleric to whom you wish to give the cleric stronghold (Anomen or Aerie) in your party when you first go to the Temple District and hear Gaal's speech.
In the unmodded game, with Throne of Bhaal, Aerie's soundset undergoes some changes at a certain point in Chapter Eight, and Anomen's soundset undergoes substantially more extensive changes as soon as Chapter Eight begins if he is Chaotic Neutral. With the Soundset Changes optional component of this mod, their soundsets change as a result of events associated with their strongholds instead. (This will not change Anomen's soundset if he is not Chaotic Neutral, nor will it interfere in any way with their soundsets changing as they do in the unmodded game, should you bring the characters along but not give them strongholds.)
Frequently Asked Questions
Q: What's this mod about?
A: In the unmodded game, the PC can gain one stronghold determined by the PC's class. This mod will permit most NPC party members to claim the strongholds appropriate for their classes.
Q: What about characters with more than one class, like Jaheira or Jan? Will they be able to claim both strongholds?
A: No. Like the PC, such characters will only be able to claim one stronghold--either of the two they qualify for.
Q: Will every NPC be able to claim a stronghold?
A: No. A few NPCs don't make sense for the strongholds their classes otherwise qualify them for, either because the stronghold-granter would not give the stronghold to that NPC or because the NPC wouldn't accept the stronghold. Logic is given priority over giving a stronghold to all NPCs in these cases.
Q: How will we know if an NPC doesn't qualify for a stronghold?
A: Either the stronghold-granter or the NPC will make it plain. The NPC will not be ignored.
Q: What if both the PC and one or more NPCs qualify for a stronghold?
A: The stronghold will be initially offered to the PC. The PC will be able to claim the stronghold, or to have an NPC who qualifies for it take it instead.
Q: Can your PC prevent the NPC from claiming the stronghold? (If you want to 'save' him/her for the second class stronghold.)
Q: Will the NPC truly run the stronghold, or will the PC make all the decisions?
A: The NPC will run the stronghold. Some NPCs will be more eager to take or ask for advice from the PC than others. In many cases, the PC will be able to have some effect on how the NPC resolves the stronghold quests--however, the ultimate decisions lie with the NPC.
Q: What happens if more than one NPC qualifies for the stronghold?
A: The stronghold will be offered to one of them initially. The PC will be able to determine which of them actually gets it.
Q: Will the pc be able to offer their input on every decision in the stronghold, or is it just the major ones?
A: That depends on the particular NPC's personality. It's also possible the PC won't be consulted at all.
Q: Will what the npc thinks of the pc (romances, alignment, charisma etc.) affect how much they listen to the pc's input?
A: In some cases.
Q: Will LG Anomen be able to gain access to the paladin stronghold? Although not a paladin, he is a member of the order.
A: No, not being a paladin (and lacking both innate Detect Evil and a personal interest in Carsomyr), Anomen will not be offered the paladin stronghold.
Q: Keldorn is already a member of the order--how can he join it?
A: He won't join the Order the same way the PC does, but the Prelate will send him on the stronghold quests after visiting the Windspear Hills.
Q: How will siding with Bodhi affect the Thieves' Guild stronghold?
A: I'm uncertain of the current patch status of the "if you have the Thieves' Guild, you can mysteriously keep it after the Shadow Thieves have been destroyed" bug...but not uncertain that it is a bug. Accordingly, if you get the Thieves' Guild for Nalia or Jan and then side with Bodhi, they will lose the stronghold. (To get the stronghold for Imoen, you will need to side with the Shadow Thieves and do the stronghold quest in Chapter Six with her in the party.)
I do consider it a problem that this will result in this mod taking "you probably don't want to side with Bodhi if the PC is a thief" to "you probably don't want to side with Bodhi," but, it's a matter of which alternative I dislike the least.
Q: Will NPCs fight duels with each other/with the PC over strongholds?
Q: What about mod NPCs?
A: Material granting a stronghold to at least one mod NPC will be forthcoming, perhaps more.
Q: Will NPCs push me to go to their strongholds for their quests?
A: Yes. This mod is not recommended for someone who sees the PC as a dictator or military commander. The spotlight is on the NPCs, and the PC's role here is secondary.
Q: Will the NPCs do remarkable things with their strongholds that the PC couldn't do? Will any NPCs get strongholds that aren't available to a PC of any class?
A: Mostly, the quests and decisions to make will be the same for an NPC that they are for the PC. The big exception to this is the Thieves' Guild stronghold, which largely presumes that the PC is a particular type of character (selfish, ruthless, and profit-motivated); while I can see Jan focusing on making his guild profitable and not rocking the boat, that really doesn't work for Imoen or Nalia. For all the strongholds, there are likely to be small changes in a number of places where the PC's limitations, in my opinion, make little or no sense. There will be no completely new strongholds.
Q: Will this mod give me a chance to kill an NPC who I couldn't kill previously with no consequences, such as Raelis Shai, Delcia Caan, Prelate Wesselan, or the Mayor of Imnesvale?
A: I wouldn't count on it.
Q: Will this mod be compatible with all other mods? With Big Picture?
A: See "Compatibility" section above.
Q: How will this mod interact with the de'Arnise Romance mod?
A: If you have both installed, whether you even see the option to offer the de'Arnise Keep to anyone but your character will depend on your character's class; you should still be able to take the Keep for your main character regardless. Note that if you do give the Keep to Mazzy or Jaheira or Anomen (or, indeed, do anything but take the Keep for your character, by design of the de'Arnise Romance mod), that will shut off the romance with Nalia.
Q: Will the new Enhanced Edition NPCs get strongholds?
A: Signs point to "no."
