I believe I have accidentally sold the Mangus Sword to the armory before i received the Quest to bring it to him. What are the ramifications of this? Can it be fixed? Do I start over? Any help would be appreciated! Thanks

Check to see if the merchant doesn't have it for sale - they seem to offer for sale the things you have sold them.
Good luck!

If that sword was a rapier, then I have tried that.

I think its impossible that you get the sword before you got the Quest. The same happend to me: I got the quest for the Mangus Sword after i finished the crypt. So I had to go back into the crypt again.. and o wonder there was the sword. (It wasn't there before i got the quest). so simply go back to the crypt again.

The same thing happened to me, go back after receiving the quest, it's there!
