Here's one I made earlier:
1. Dwarves have never taken to these.
2. It betrays in the roundest manner.
3. Narnian prince begins to reside in hobbit dwellings? Such a mingling! See them shine!
4. Heavenly start to December contrives to shield a mariner’s sword.
5. Leader in disarray gains a thousand: a jewel to adorn a steersman.
6. Lalaith in the dark land? Serves quarrellers right, some might say!
7. Objects of heavenly beings impersonating Miss Nightingale?
8. Sounds like Noah’s vessel cast in granite! Resplendent thing.
9. Day’s opposite becomes null, in song.
10. Happy days, and light ones.
