Den of Geek article had some fun with anagrams of Trenzalore. ("Learnt zero" and "Real Zen crap", for instance.) How about "Fields of Trenzalore"? I tried it out and learned something very important: the human mind is excellent at making connections that don't exist, finding meaning where there is none. Here are my faves:
Frozen tears, old life - Most angsty!
Frozen fears, told lie - The Doctor lied about his name!
A frozen doll set fire - Our arch-villain is a doll
Soldier Zero left fan - Remember Prisoner Zero? Well, he got put in jail because he left a fan behind
Left ear frozen solid - The Doctor whispered his name into River Song's ear, but it was frozen solid so everyone is safe
The word TARDIS is in there too, but I didn't go there.
