Hi Dillon
Just a note b4 i post. Could you use a different font color? Black is kinda hard to read, slightly annoying having to highlight each of ur questions between my typing.
Alright on to the questions. As for ur ore, yes. You can find a couple of deposits to make up for the ones you might have missed. See [url="http://www.gamebanshee.com/neverwinternights2/walkthrough/ore.php"]here[/url] to find any ore deposits you might still retrieve from previous acts.
I can't recall needing resources to rebuild and fortify the keep. Apart from gold that is. I could be wrong tho, its been sometime since i played. Don't worry bout the keep time. It will be static if there is something you need to do that is crucial to the main questline. For example it stops on 27% (I think) the 1st time around until you finish a certain main quest. In other words, you will have done all the important quests by the time the keep time hits 100%
I assume you killed the drunken sergeant? Slight spoiler (highlight to read)
The sergeant accompanying Sydney Natale. His name was Jalboun i think.
If he is indeed the one you killed you can still recruit Katriona, Casavir's old lieutenant. Each sergeant is proficient in a different role. Use Bevil to guard the roads, Light of Heavans to recruit and Katriona to train. As long as you have enough well trained men in ur keep, the safety of the roads and lands will improve. Regardless of how you assigned Bevil (either land or road)
Finally, if you want, you can tweak a game file to give you the best of the best. Full trained men, countless soldiers, best morale, reverse keep time and whatnot. But thats just plain cheating lol. And i can't really remember how to tweak the file, or what it is in the 1st place...
Hope that helps.
