Sorry if this has been addressed, but I can't get the search feature to work.

 

I've finished WGS and would like to go through the MIthril door (though my smithing still isn't high enough to do anything in there).

 

But I can't find my Dragonkin key. Either I lost it or never got it. The Tip.it items guide does not mention how to get it back if you lose it.

 

Any ideas?

You should go back to the Movario's base and search it- I think it's near the bed (or in it), I had a similar problem but I found it there after losing it.
