I'm in a similar boat. I dismantled mine while trying to clean up my inventory and I hadn't locked it yet. I'm a little annoyed that there is no way to reacquire this weapon especially because it's needed to start a quest line. I feel this is something that should be addressed. edit: I have three characters and will be getting two of the three swords. I don't want to delete any of my characters to get the third because it would result in me losing the data and statistics linked to that character.
