Back a while ago I got the opportunity to go on the second harper quest (Given by Xzar to rescue Montaran). Well, I declined, stupid me. Can anyone write an NPC script that acts in such a way as to place Xzar back in the game where he first finds you? If someone could do this I would be quite grateful. Thanks alot!

Don't know if this will work, but you might be able to use the CreateCreature cheat to create another Xzar. Unfortunately, I don't have ShadowKeeper with me so I don't have the exact code, sorry.

Wait a moment....shouldn't Xzar still be available after you decline him? He just stand around the corner of the stairs....unless you attacked him......
If you have declined initially and Xzar appeared to have walked away, try visiting the spot that he appeared after a while (couple of days maybe) and he should be back. I think this happened to me when I first played the game....since I never really liked him in BGI.

Still wondering...

I declined his offer several times, but he always stayed in the same spot. I don't know what to do if he's disappeared.
