He came in with a project in mind.  After years of being single he met his soulmate.   They were going on a trip and he wanted to propose at Stonehenge.   What kind of mythical lore could we use for the ring.   An ouroboros - of course!   This creature is the embodiment of the circle of life.  He also had a piece of meteorite that he'd found as a kid.  That's what we inlaid on the top of the head.   
When the got to Stonehenge he was too nervous and just couldn't find the right time.  The guards try and get people in and out so that all can see the site.   When they were exiting the guard asked him "why the long face"?  After explaining his predicament a miracle happened.  The guard issued everyone (but them) out and gave them a few moments alone there.    He dropped down on one knee.  She said "YES" and the rest is romantic history.   I'm writing this after their 5th anniversary and they're still very much in love.   Thanks for letting me play a small role in your story.
