Got this as a frimp in my order that arrived yesterday, and as a Lovecraft fan who wants to try ALL THE ARKHAM SCENTS, I was pretty excited.  This is also my first review, so sorry if I do it wrong/weird! 
  
In the bottle:  A bit salty, very evocative of the beach and seawater. 
  
Wet on skin:  Very similar to what I smelled in the bottle.  A little bit less salty, but I could still smell it.  Visions of murky underwater landscapes with seaweed floating across my view. 
  
Dry on skin:  Seems to alternate between the previous murky seawater and a cleaner sea smell.  Reminds me of Mary Read, but a little less feminine, more straight oceanic.  Remained with very little fading for hours.  Put it on at about 2:30 pm, could still smell it just the same when I went to bed.  In fact, I sniffed the crook of my elbow this morning and it was still there, faintly!  A little will go a long way   
  
Verdict:  Nice!  I'll continue to love my Mary Read but this imp will get used when I want to be a little less feminine and more unabashedly Order-of-Dagon-ish
