I read the wikki and it says you just have to wait for 30 in game days and it will appear. It's unclear whether you must kill the werewolf or not, so I let him live. I came back 30 days later and it's still not there, neither is the satue of Talos, although the chest has reset.
So my question is should the blade be there if the werewolf is still there or do I have to kill him? I don't want to wait another 30 days so I won't bother killing him either way. Are there any other one handed katans that I can get without the main quest or that one guy at that inn (forget his name). Don't really want to murder him just for a sword.
Thanks.
Note: I did a search on the topic but it was unclear if the blade would appear while the werewolf still lived.
